Have a look to headline framework as an example or staring point. hlparsetext() returns parsed text with matched lexemes in tsquery. Small description of hlparsetext is placed at http://www.sai.msu.su/~megera/postgres/gist/tsearch/V2/docs/HOWTO-parser-tsearch2.html near the end. Description of HLWORD struct is some out of day, sorry. -- Teodor Sigaev E-mail: teodor@sigaev.ru WWW: http://www.sigaev.ru/
