tsearch_extras

The package provides a few PostgreSQL functions that allow you to get at lower-level data about full text search.

The currently available functions are:

Function	Description
ts_match_locs_array(regconfig, text, tsquery)	Returns the locations and lengths of matches as an array of 2-element arrays
ts_match_locs_array(text, tsquery)	Same as above, but with the current text search configuration
tsvector_lexemes(tsvector)	Returns an array of the lexemes in the given tsvector

Examples

pgdb=> SELECT ts_match_locs_array('The quick brown fox jumped over the lazy dog.  The jumping was quite fast.',
                                  plainto_tsquery('jump'));
