Example parser ============== This is an example of a custom parser for full text search. It recognizes space-delimited words and returns only two token types: - 3, word, Word - 12, blank, Space symbols The token numbers have been chosen to keep compatibility with the default ts_headline() function, since we do not want to implement our own version. * Configuration The parser has no user-configurable parameters. * Usage 1. Compile and install 2. Load dictionary psql mydb < test_parser.sql 3. Test it mydb# SELECT * FROM ts_parse('testparser','That''s my first own parser'); tokid | token -------+-------- 3 | That's 12 | 3 | my 12 | 3 | first 12 | 3 | own 12 | 3 | parser mydb# SELECT to_tsvector('testcfg','That''s my first own parser'); to_tsvector ------------------------------------------------- 'my':2 'own':4 'first':3 'parser':5 'that''s':1 mydb# SELECT ts_headline('testcfg','Supernovae stars are the brightest phenomena in galaxies', to_tsquery('testcfg', 'star')); headline ----------------------------------------------------------------- Supernovae <b>stars</b> are the brightest phenomena in galaxies That's all.
