further tweak search containing very frequent tokens
...
Excluding non-rare full names is not really possible because it makes
addresses with street names like 'main st' unsearchable. This tries to
leav all names in but refrain from ordering results by accuracy
when too many results are expected. This means that the DB will simply
get the first n results without any particular order.

real counts.

remove lookup by address only

There are too many lookups where the address is very frequent,
even when many address parts are present.

do not lookup by address vector when only few tokens are available
...
Names of countries and states are exceedingly rare in the word count
but are very frequent in the address. A short name has the danger
of producing too many results.

Give a preference to left-right reading, i.e <postcode>,<address>
prefers a postcode search while <address>,<postcode> rather does
an address search.

postcode is contained in the query.
