Re: Install Tsearch2

I believe I followed these instructions the last time I enabled tsearch2:

http://www.sai.msu.su/~megera/wiki/tsearch-v2-intro

These are my crib notes for the English version, you'll have to update paths
etc:

wget http://www.sai.msu.su/~megera/postgres/gist/tsearch/V2/dicts/ispell/ispell-english.tar.gz
cd /usr/local/lib
sudo tar xvfz /usr/local/src/TARFILES/ispell-english.tar.gz

psql -f /usr/share/pgsql/contrib/tsearch2.sql ftstest

INSERT INTO pg_ts_cfg (ts_name , prs_name, locale ) values ( 'default_english', 'default', 'en_US');

INSERT INTO pg_ts_dict
        (SELECT 'en_ispell',
            dict_init,
            'DictFile="/usr/local/lib/english.dict",'
            'AffFile="/usr/local/lib/english.aff",'
            'StopFile="/usr/share/pgsql/contrib/english.stop"',
            dict_lexize
     FROM pg_ts_dict
     WHERE dict_name = 'ispell_template');

INSERT INTO pg_ts_cfgmap (ts_name, tok_alias, dict_name)
        VALUES ('default_english', 'lhword', '{en_ispell,en_stem}');
INSERT INTO pg_ts_cfgmap (ts_name, tok_alias, dict_name)
        VALUES ('default_english', 'lpart_hword', '{en_ispell,en_stem}');
INSERT INTO pg_ts_cfgmap (ts_name, tok_alias, dict_name)
        VALUES ('default_english', 'lword', '{en_ispell,en_stem}');

INSERT INTO pg_ts_cfgmap
        VALUES ('default_english', 'url', '{simple}');
INSERT INTO pg_ts_cfgmap
        VALUES ('default_english', 'host', '{simple}');
INSERT INTO pg_ts_cfgmap
        VALUES ('default_english', 'sfloat', '{simple}');
INSERT INTO pg_ts_cfgmap
        VALUES ('default_english', 'uri', '{simple}');
INSERT INTO pg_ts_cfgmap
        VALUES ('default_english', 'int', '{simple}');
INSERT INTO pg_ts_cfgmap
        VALUES ('default_english', 'float', '{simple}');
INSERT INTO pg_ts_cfgmap
        VALUES ('default_english', 'email', '{simple}');
INSERT INTO pg_ts_cfgmap
        VALUES ('default_english', 'word', '{simple}');
INSERT INTO pg_ts_cfgmap
        VALUES ('default_english', 'hword', '{simple}');
INSERT INTO pg_ts_cfgmap
        VALUES ('default_english', 'nlword', '{simple}');
INSERT INTO pg_ts_cfgmap
        VALUES ('default_english', 'nlpart_hword', '{simple}');
INSERT INTO pg_ts_cfgmap
        VALUES ('default_english', 'part_hword', '{simple}');
INSERT INTO pg_ts_cfgmap
        VALUES ('default_english', 'nlhword', '{simple}');
INSERT INTO pg_ts_cfgmap
        VALUES ('default_english', 'file', '{simple}');
INSERT INTO pg_ts_cfgmap
        VALUES ('default_english', 'uint', '{simple}');
INSERT INTO pg_ts_cfgmap
        VALUES ('default_english', 'version', '{simple}');

ALTER TABLE album ADD COLUMN idxFTI tsvector;
UPDATE album SET idxFTI=to_tsvector(name);
CREATE INDEX album_idxFTI_idx ON album USING gist(idxFTI);

CREATE TRIGGER album_tsvectorupdate BEFORE UPDATE OR INSERT ON album
             FOR EACH ROW EXECUTE PROCEDURE tsearch2(idxFTI, name);

SELECT * FROM album WHERE idxfti @@ to_tsquery('spiderman');


Hopefully that helps...
