The class parameter was used as is, allowing for potential
SQL injection via the API.

+# Fallback Country Boundaries
+
+Each place is assigned a `country_code` and partition. Partitions derive from `country_code`.
+
+Nominatim imports two pre-generated files
+
+   * `data/country_name.sql` (country code, name, default language, partition)
+   * `data/country_osm_grid.sql` (country code, geometry)
+
+before creating places in the database. This helps with fast lookups and missing data (e.g. if the data the user wants to import doesn't contain any country places).
+
+The number of countries in the world can change (South Sudan created 2011, Germany reunification), so can their boundaries. This document explain how the pre-generated files can be updated.
+
+
+
+## Country code
+
+Each place is assigned a two letter country_code based on its location, e.g. `gb` for Great Britain. Or `NULL` if no suitable country is found (usually it's in open water then).
+
+In `sql/functions.sql: get_country_code(geometry)` the place's center is checked against
+
+   1. country places already imported from the user's data file. Places are imported by rank low-to-high. Lowest rank 2 is countries so most places should be matched. Still the data file might be incomplete.
+   2. if unmatched: OSM grid boundaries
+   3. if still unmatched: OSM grid boundaries, but allow a small distance
+
+
+
+## Partitions
+
+Each place is assigned partition, which is a number 0..250. 0 is fallback/other.
+
+During place indexing (`sql/functions.sql: placex_insert()`) a place is assigned the partition based on its country code (`sql/functions.sql: get_partition(country_code)`). It checks in the `country_name` table.
+
+Most countries have their own partition, some share a partition. Thus partition counts vary greatly.
+
+Several database tables are split by partition to allow queries to run against less indices and improve caching.
+
+   * `location_area_large_<partition>`
+   * `search_name_<partition>`
+   * `location_road_<partition>`
+
+
+
+
+
+## Data files
+
+### data/country_name.sql
+
+Export from existing database table plus manual changes. `country_default_language_code` most taken from [https://wiki.openstreetmap.org/wiki/Nominatim/Country_Codes](), see `utils/country_languages.php`.
+
+
+
+### data/country_osm_grid.sql
+
+`country_grid.sql` merges territories by country. Then uses `function.sql: quad_split_geometry` to split each country into multiple [Quadtree](https://en.wikipedia.org/wiki/Quadtree) polygons for faster point-in-polygon lookups.
+
+To visualize one country as geojson feature collection, e.g. for loading into [geojson.io](http://geojson.io/):

+# GB Postcodes
+
+
+The server [importing instructions](https://www.nominatim.org/release-docs/latest/admin/Import-and-Update/) allow optionally download [`gb_postcode_data.sql.gz`](https://www.nominatim.org/data/gb_postcode_data.sql.gz). This document explains how the file got created.
+
+## GB vs UK
+
+GB (Great Britain) is more correct as the Ordnance Survey dataset doesn't contain postcodes from Northern Ireland.
+
+## Importing separately after the initial import
+
+If you forgot to download the file, or have a new version, you can import it separately:
+
+1. Import the downloaded `gb_postcode_data.sql.gz` file.
+
+2. Run the SQL query `SELECT count(getorcreate_postcode_id(postcode)) FROM gb_postcode;`. This will update the search index.
+
+3. Run `utils/setup.php --calculate-postcodes` from the build directory. This will copy data form the `gb_postcode` table to the `location_postcodes` table.
+
+
+
+## Converting Code-Point Open data
+
+1. Download from [Code-Point® Open](https://www.ordnancesurvey.co.uk/business-and-government/products/code-point-open.html). It requires an email address where a download link will be send to.
+
+2. `unzip codepo_gb.zip`
+
+    Unpacked you'll see a directory of CSV files.
+
+        $ more codepo_gb/Data/CSV/n.csv
+        "N1 0AA",10,530626,183961,"E92000001","E19000003","E18000007","","E09000019","E05000368"

+
+    The coordinates are "Northings" and "Eastings" in [OSGB 1936](http://epsg.io/1314) projection. They can be projected to WGS84 like this

+# US TIGER address data
+
+Convert [TIGER](https://www.census.gov/geo/maps-data/data/tiger.html)/Line dataset of the US Census Bureau to SQL files which can be imported by Nominatim. The created tables in the Nominatim database are separate from OpenStreetMap tables and get queried at search time separately.
+
+The dataset gets updated once per year. Downloading is prown to be slow (can take a full day) and converting them can take hours as well.
+
+Replace '2018' with the current year throughout.
+
+  1. Install the GDAL library and python bindings and the unzip tool
+
+        # Ubuntu:
+        sudo apt-get install python-gdal unzip
+        # CentOS:
+        sudo yum install gdal-python unzip
+
+  2. Get the TIGER 2018 data. You will need the EDGES files
+     (3,233 zip files, 11GB total).
+
+         wget -r ftp://ftp2.census.gov/geo/tiger/TIGER2018/EDGES/
+
+  3. Convert the data into SQL statements. Adjust the file paths in the scripts as needed
+
+        cd data-sources/us-tiger
+        ./convert.sh <input-path> <output-path>

+## Choosing the Data to Import
+
+In its default setup Nominatim is configured to import the full OSM data
+set for the entire planet. Such a setup requires a powerful machine with
+at least 32GB of RAM and around 800GB of SSD hard disks. Depending on your
+use case there are various ways to reduce the amount of data imported. This
+section discusses these methods. They can also be combined.
+
+### Using an extract
+
+If you only need geocoding for a smaller region, then precomputed extracts
+are a good way to reduce the database size and import time.
+[Geofabrik](https://download.geofabrik.de) offers extracts for most countries.
+They even have daily updates which can be used with the update process described
+below. There are also
+[other providers for extracts](https://wiki.openstreetmap.org/wiki/Planet.osm#Downloading).
+
+Please be aware that some extracts are not cut exactly along the country
+boundaries. As a result some parts of the boundary may be missing which means
+that cannot compute the areas for some administrative areas.
+
+### Dropping Data Required for Dynamic Updates
+
+About half of the data in Nominatim's database is not really used for serving
+the API. It is only there to allow the data to be updated from the latest
+changes from OSM. For many uses these dynamic updates are not really required.
+If you don't plan to apply updates, the dynamic part of the database can be
+safely dropped using the following command:
+
+```
+./utils/setup.php --drop
+```
+
+Note that you still need to provide for sufficient disk space for the initial
+import. So this option is particularly interesting if you plan to transfer the
+database or reuse the space later.
+
+### Reverse-only Imports
+
+If you only want to use the Nominatim database for reverse lookups or
+if you plan to use the installation only for exports to a
+[photon](http://photon.komoot.de/) database, then you can set up a database
+without search indexes. Add `--reverse-only` to your setup command above.
+
+This saves about 5% of disk space.
+
+### Filtering Imported Data
+
+Nominatim normally sets up a full search database containing administrative
+boundaries, places, streets, addresses and POI data. There are also other
+import styles available which only read selected data:
+
+* **settings/import-admin.style**
+  Only import administrative boundaries and places.
+* **settings/import-street.style**
+  Like the admin style but also adds streets.

+# OSM Data Import
+
+OSM data is initially imported using osm2pgsql. Nominatim uses its own data
+output style 'gazetteer', which differs from the output style created for
+map rendering.
+
+## Database Layout
+
+The gazetteer style produces a single table `place` with the following rows:
+
+ * `osm_type` - kind of OSM object (**N** - node, **W** - way, **R** - relation)
+ * `osm_id` - original OSM ID
+ * `class` - key of principal tag defining the object type
+ * `type` - value of principal tag defining the object type
+ * `name` - collection of tags that contain a name or reference
+ * `admin_level` - numerical value of the tagged administrative level
+ * `address` - collection of tags defining the address of an object
+ * `extratags` - collection of additional interesting tags that are not
+                 directly relevant for searching
+ * `geometry` - geometry of the object (in WGS84)
+
+A single OSM object may appear multiple times in this table when it is tagged
+with multiple tags that may constitute a principal tag. Take for example a
+motorway bridge. In OSM, this would be a way which is tagged with
+`highway=motorway` and `bridge=yes`. This way would appear in the `place` table
+once with `class` of `highway` and once with a `class` of `bridge`. Thus the
+*uique key* for `place` is (`osm_type`, `osm_id`, `class`).
+
+## Configuring the Import
+
+How tags are interpreted and assigned to the different `place` columns can be
+configured via the import style configuration file (`CONST_Import_style`). This
+is a JSON file which contains a list of rules which are matched against every
+tag of every object and then assign the tag its specific role.
+
+### Configuration Rules
+
+A single rule looks like this:
+
+```json
+{
+    "keys" : ["key1", "key2", ...],
+    "values" : {
+        "value1" : "prop",
+        "value2" : "prop1,prop2"
+    }
+}
+```
+
+A rule first defines a list of keys to apply the rule to. This is always a list
+of strings. The string may have four forms. An empty string matches against
+any key. A string that ends in an asterisk `*` is a prefix match and accordingly
+matches against any key that starts with the given string (minus the `*`). A
+suffix match can be defined similarly with a string that starts with a `*`. Any
+other string constitutes an exact match.
+
+The second part of the rules defines a list of values and the properties that
+apply to a successful match. Value strings may be either empty, which again
+means that thy match against any value, or describe an exact match. Prefix
+or suffix matching of values is not possible.
+
+For a rule to match, it has to find a valid combination of keys and values. The
+resulting property is that of the matched values.
+
+The rules in a configuration file are processed sequentially and the first
+match for each tag wins.
+
+A rule where key and value are the empty string is special. This defines the
+fallback when none of the rules matches. The fallback is always used as a last
+resort when nothing else matches, no matter where the rule appears in the file.
+Defining multiple fallback rules is not allowed. What happens in this case,
+is undefined.
+
+### Tag Properties
+
+One or more of the following properties may be given for each tag:
+
+* `main`
+
+    A principal tag. A new row will be added for the object with key and value
+    as `class` and `type`.
+
+* `with_name`
+
+    When the tag is a principal tag (`main` property set): only really add a new
+    row, if there is any name tag found (a reference tag is not sufficient, see
+    below).
+
+* `with_name_key`
+
+    When the tag is a principal tag (`main` property set): only really add a new
+    row, if there is also a name tag that matches the key of the principal tag.
+    For example, if the main tag is `bridge=yes`, then it will only be added as
+    an extra row, if there is a tag `bridge:name[:XXX]` for the same object.
+    If this property is set, all other names that are not domain-specific are
+    ignored.
+
+* `fallback`
+
+    When the tag is a principal tag (`main` property set): only really add a new
+    row, when no other principal tags for this object have been found. Only one
+    fallback tag can win for an object.
+
+* `operator`
+
+    When the tag is a principal tag (`main` property set): also include the
+    `operator` tag in the list of names. This is a special construct for an
+    out-dated tagging practise in OSM. Fuel stations and chain restaurants
+    in particular used to have the name of the chain tagged as `operator`.
+    These days the chain can be more commonly found in the `brand` tag but
+    there is still enough old data around to warrant this special case.
+
+* `name`
+
+    Add tag to the list of names.
+
+* `ref`
+
+    Add tag to the list of names as a reference. At the moment this only means
+    that the object is not considered to be named for `with_name`.
+
+* `address`
+
+    At tag to the list of address tags. If the tag starts with `addr:` or
+    `is_in:`, then this prefix is cut off before adding it to the list.
+
+* `postcode`
+
+    At the value as a postcode to the address tags. If multiple tags are
+    candidate for postcodes, one wins out and the others are dropped.
+
+* `country`
+
+    At the value as a country code to the address tags. The value must be a
+    two letter country code, otherwise it is ignored. If there are multiple
+    tags that match, then one wins out and the others are dropped.
+
+* `house`
+
+    If no principle tags can be found for the object, still add the object with
+    `class`=`place` and `type`=`house`. Use this for address nodes that have no
+    other function.
+
+* `interpolation`
+
+    Add this object as an address interpolation (appears as `class`=`place` and
+    `type`=`houses` in the database).
+
+* `extra`
+
+    Add tag to the list of extra tags.
+
+* `skip`
+
+    Skip the tag completely. Useful when a custom default fallback is defined
+    or to define exceptions to rules.
+
+A rule can define as many of these properties for one match as it likes. For
+example, if the property is `"main,extra"` then the tag will open a new row
+but also have the tag appear in the list of extra tags.
+
+There are a number of pre-defined styles in the `settings/` directory. It is
+advisable to start from one of these styles when defining your own.
+
+### Changing the Style of Existing Databases
+
+There is normally no issue changing the style of a database that is already
+imported and now kept up-to-date with change files. Just be aware that any
+change in the style applies to updates only. If you want to change the data
+that is already in the database, then a reimport is necessary.

+# Place Ranking in Nominatim
+
+Nominatim uses two metrics to rank a place: search rank and address rank.
+Both can be assigned a value between 0 and 30. They serve slightly
+different purposes, which are explained in this chapter.
+
+## Search rank
+
+The search rank describes the extent and importance of a place. It is used
+when ranking search result. Simply put, if there are two results for a
+search query which are otherwise equal, then the result with the _lower_
+search rank will be appear higher in the result list.
+
+Search ranks are not so important these days because many well-known
+places use the Wikipedia importance ranking instead.
+
+## Address rank
+
+The address rank describes where a place shows up in an address hierarchy.
+Usually only administrative boundaries and place nodes and areas are
+eligible to be part of an address. All other objects have an address rank
+of 0.
+
+Note that the search rank of a place place a role in the address computation
+as well. When collecting the places that should make up the address parts
+then only places are taken into account that have a lower address rank than
+the search rank of the base object.
+
+## Rank configuration
+
+Search and address ranks are assigned to a place when it is first imported
+into the database. There are a few hard-coded rules for the assignment:
+
+ * postcodes follow special rules according to their length
+ * boundaries that are not areas and railway=rail are dropped completely
+ * the following are always search rank 30 and address rank 0:
+    * highway nodes
+    * landuse that is not an area
+
+Other than that, the ranks can be freely assigned via the json file
+defined with `CONST_Address_Level_Config` according to their type and
+the country they are in.
+
+The address level configuration must consist of an array of configuration
+entries, each containing a tag definition and an optional country array:
+
+```
+[ {
+    "tags" : {
+      "place" : {
+        "county" : 12,
+        "city" : 16,
+      },
+      "landuse" : {
+        "residential" : 22,
+        "" : 30
+      }
+    }
+  },
+  {
+    "countries" : [ "ca", "us" ],
+    "tags" : {
+      "boundary" : {
+        "administrative8" : 18,
+        "administrative9" : 20
+      },
+      "landuse" : {
+        "residential" : [22, 0]
+      }
+    }
+  }
+]
+```
+
+The `countries` field contains a list of countries (as ISO 3166-1 alpha 2 code)
+for which the definition applies. When the field is omitted, then the
+definition is used as a fallback, when nothing more specific for a given
+country exists.
+
+`tags` contains the ranks for key/value pairs. The ranks can be either a
+single number, in which case they are to search and address rank, or a tuple
+of search and address rank (in that order). The value may be left empty.
+Then the rank is used when no more specific value is found for the given
+key.
+
+Countries and key/value combination may appear in multiple defintions. Just
+make sure that each combination of counrty/key/value appears only once per
+file. Otherwise the import will fail with a UNIQUE INDEX constraint violation
+on import.
