It's not supposed usage... Why do you need that?

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.
