don't restrict to viewbox for frequent terms
...
All searched places may be outside the viewbox in which case the
restriction means that there are no results at all. Add the penalty for
being outside the viewbox earlier instead and then cut the list.

increase penalty on mismatching postcodes for address searches

Sorting them by presence of housenumber only will give an undue

add direction penalties
...
Direction penalties are estimated by getting the name to address
ratio usage for each partial term in the query and computing the
linear regression of that ratio over the entire phrase. Or to put
it in ither words: we try to determine if the terms at the beginning
or the end of the query are more likely to constitute a name.
Direction penalties are currently used only in classic name queries.
