Hi,
I am using Postgres' full text search since some time now and overall it's
working really well for me. However one issue I have is that ts_headline
highlights partial matches of FOLLOWED BY (<->) expressions, e.g.
SELECT ts_headline('some words and some more words',
to_tsquery('some<->words'));
gives
<b>some</b> <b>words</b> and <b>some</b> more <b>words</b>
while I expect
<b>some words</b> and some more words
I think the highlights of partial matches is in most cases not useful and
confusing to end users, they may think the search did not recognize they
requested the words to be consecutive. Google also does not highlight partial
matches it seems.
I suspect to implement this would require substantial changes to ts_headline
since it seems to treat the lexemes independently, but it would be a big
improvement and should be the default behaviour.
Best regards,
Jake N
