I'm fiddling with to_tsvector() and parse() from tsearch2, trying to get
the word position from those functions. I'd like to use the tsearch2
parser and stemmer, but I need to know the exact position of the word as
well as the original, unstemmed word.
It's not supposed usage... Why do you need that?
And this only tells me a word position, not a character or byte position
within the string. Is there a way to get this information from tsearch2?
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.
