Subject: remove unused columns in search_name_* and use right index
X-Git-Tag: v3.6.0~32^2~2
X-Git-Url: https://git.openstreetmap.org/nominatim.git/commitdiff_plain/9160cce6d882d0bfe999c86ae976b392e0cddd89

remove unused columns in search_name_* and use right index

We only need the address rank these days, so get rid of
search rank. Also switch indexes to work on address rank.
