Excerpts not working on partial matches?

[Christophe Porteneuve]

Hi all,

I've very recently got on the TS train, and am loving it. It sure
helps that in the past few years a lot of good doc's been written and
updated :-)

My app basically always works using partial matches (prefix only) with
a minimum matching length of 4. I don't require final users to type
in the star signs, and just add them internally to all the terms of
the query, which runs in expended match mode.

I do fetch all the fields displayed in the results page through
excerpts, to get highlighted matches (and configured TS to strip_html
before that). However, it seems that excerpts only work on full
matches, not on partial matches.

Ideally, I'd want to get full-word matches of my partial segments, and
less ideally, just partial-match excerpts.

For instance, if I search for "install" and it matches thanks to
"installation", I'd love to get the full word highlighted, or less
ideally, the "install" part of it.

Must I reprocess the returned excerpts myself to do this, or is there
a tiny config tweak I missed?

Thanks!

Hi Christophe

If it's not working, it's a limitation in Sphinx, not Thinking
Sphinx... so I've gone searching on the Sphinx forums, sounds like it
*might* work with 0.9.9, but definitely not with 0.9.8.

So, are you using the latest 0.9.9 release candidate (with the
sphinx-0.9.9 branch of TS)? If so, then it's probably worth posting on
the Sphinx forum. If not, sounds like upgrading is a good place to
start.

Cheers

Hey Pat, thanks for your ever speedy reply!

This is my first TS deployment and I'm not so sure I want to rely on a
version not yet guaranteed as stable, from a client-explanation POV :-)
So I think in the meantime I *will* just manually rehighlight obtained
excerpts, and track 0.9.9's stable status.

Cheers!
