Empty results OMEGA with XAPIAN 1.0.1

Hi,

I configured XAPIAN 1.0.1 and OMEGA 1.0.1. on my development
machine
(first removed the old ones). I recreated my databases (both
quartz
and flint) and tried to run original queries against the
databases
created by the new versions.

I'm getting empty result sets from OMEGA. If I use the delve
tool I
actually see that the records are created fine. No log files
are
written as far as I know. Are there any methods to debug
this?

I've tried running OMEGA 1.0.1 against a XAPIAN 0.9.9
database and
this works fine, so I guess the problem lies with XAPIAN.

Regards,

Maarten

Odd, I upgraded xapian.org to 1.0.1 yesterday and that
worked.

Does it just return "no matches", or no output at
all?

You could try the "quest" example, which uses the
QueryParser class
too.

Also, you could try running Omega from the command line, in
case
there's some output to stderr.

Also, you can add $querydescription to your OmegaScript
template
which shows how the query gets parsed.

In the same place you found delve.

It returns no matches

Where do I find this example?

Yes, same result from the commandline

I'll try that. I just built the 0.9.10 version again and it
works fine
on the same databases. So the upgrade itself seems to be the
problem..

I've come to the point where the following combinations do
work:
XAPIAN 1.0.1 and OMEGA 0.9.10
XAPIAN 0.9.10 and OMEGA 1.0.1

and what not works:
XAPIAN 1.0.1 and OMEGA 1.0.1


This query:
P=mario
DB=games
FMT=searchGames.xml

results in:
$query description of XAPIAN 1.0.1 and OMEGA 1.0.1:
<desc>Xapian::Query(Zmario:(pos=1))</desc>
<previous>Zmario</previous>

$query description of XAPIAN 1.0.1 and OMEGA 0.9.10:
<desc>Xapian::Query(mario:(pos=1))</desc>
<previous>mario</previous>


So, where does this Z prefix come from?

Regards,

Maarten

That's the new term generation strategy introduced in
1.0.0:

http://
www.xapian.org/docs/termgenerator.html

Do you have your own indexer?  Are you using stemming?

I've tried it with both the dutch stemmer and no stemmer.
Same results.

I'm using the default indexer.

Cheers,

Maarten

Turns out it does work if I use --stemmer=dutch, but it
doesn't when
using --stemmer=none.
Default stemmer is english right?

Do you have any solution for this? I don't want to use the
stemmer in
some projects.

Maarten

Can you explain why you talk about the 'default' stemmer
immediately
after --stemmer=none? It's confused me.

Note that you can't change the stemmer used by scriptindex
without
making a code change at the moment. Everything else should
work, as
far as I'm aware.
