From: Sarah Hoffmann Date: Thu, 3 Sep 2020 08:38:33 +0000 (+0200) Subject: merge addr tags into search_name table X-Git-Tag: v3.6.0~70^2~1 X-Git-Url: https://git.openstreetmap.org./nominatim.git/commitdiff_plain/caea14d0357a1e0a901dfac82febc834aec95f0f?ds=sidebyside;hp=--cc merge addr tags into search_name table When a place of rank 30 has addr tags that are not covered by the search terms of the parent, add a separate entry for the POI in the search_name table that includes the addr tags. We can only do that with named places. For POIs without a name the housenumber is used as name. If that is not available either, searching still won't work. --- caea14d0357a1e0a901dfac82febc834aec95f0f diff --git a/sql/functions/normalization.sql b/sql/functions/normalization.sql index 08087172..71b14ee5 100644 --- a/sql/functions/normalization.sql +++ b/sql/functions/normalization.sql @@ -412,3 +412,99 @@ BEGIN END; $$ LANGUAGE plpgsql; + + +CREATE OR REPLACE FUNCTION create_poi_search_terms(parent_place_id BIGINT, + address HSTORE, + housenumber TEXT, + initial_name_vector INTEGER[], + OUT name_vector INTEGER[], + OUT nameaddress_vector INTEGER[]) + AS $$ +DECLARE + parent_name_vector INTEGER[]; + parent_address_vector INTEGER[]; + addr_place_ids INTEGER[]; + + addr_item RECORD; +BEGIN + -- Compute all search terms from the addr: tags. + nameaddress_vector := '{}'::INTEGER[]; + + IF address IS NOT NULL THEN + FOR addr_item IN SELECT * FROM each(address) + LOOP + IF addr_item.key IN ('city', 'tiger:county', 'state', 'suburb', 'province', + 'district', 'region', 'county', 'municipality', + 'hamlet', 'village', 'subdistrict', 'town', + 'neighbourhood', 'quarter', 'parish') + THEN + nameaddress_vector := array_merge(nameaddress_vector, + addr_ids_from_name(addr_item.value)); + END IF; + END LOOP; + END IF; + + -- If the POI is named, simply mix in all address terms and be done. + IF array_length(initial_name_vector, 1) is not NULL THEN + -- Cheating here by not recomputing all terms but simply using the ones + -- from the parent object. + SELECT array_merge(s.name_vector, s.nameaddress_vector) + INTO parent_address_vector + FROM search_name s + WHERE s.place_id = parent_place_id; + + name_vector := initial_name_vector; + nameaddress_vector := array_merge(nameaddress_vector, parent_address_vector); + + IF not address ?
