Re: how to compile java-swig under linux.

Hmm, it's there but commented out.  I tried adding it back in, but make
fails.  It looks like it no longer finds other classes in the package.
I don't really know how this is supposed to work, which is probably why
I commented out the option before.

If you want to take a look, this is the patch to Makefile.am:

http://oligarchy.co.uk/xapian/patches/java-swig-makefile-package.patch

If you make the same change to Makefile.in, you don't need to run
automake, etc which may be simpler if you don't have suitable versions
installed.

Missing Debian Packages

Hi All,

Since the xapian website outage on March 25th, I've noticed that my  
daily Debian updates are failing with 404 errors.   In fact,  http://xapian.org/debian 
  does not seem to exist.

Are there plans to restore the Debian repository?   I would like to  
update to 1.0.6, but I'm waiting for official packages first.

Thanks in advance,

Cory

P.S. http://xapian.org/search.php seems to be broken as well.

Yes (as Richard mentioned in his message).  Apologies for any
inconvenience.

They'll be restored once we can get to the old server, which seems to be
taking longer than expected.  But I haven't packaged 1.0.6 for
Debian/Ubuntu yet.

It's possible I have a copy of the 1.0.5 packages on my desktop machine,
but it's refusing to boot since being shipped to NZ, so I can't
trivially copy them off anyway.  The chroots I build packages in are on
this machine too, which is the main reason why I've not packaged 1.0.6
yet.

> P.S. http://xapian.org/search.php seems to be broken as well.

Unfortunately I couldn't find a copy of the Omega templates it uses.

Cheers,

Using special characters in query terms

Hi,

I would like to search for filenames in a xapian database.

For now my query for "foo-bar.po" turns into the following:
  Xapian::Query((foo:(pos=1) PHRASE 3 bar:(pos=2) PHRASE 3 po:(pos=3)))

This query is successful, if I used the term generator to tokenize "foo-bar.po"
during indexing.

The problem is: this workaround makes it impossible to distinguish between
"foo-bar.po" and "foo/bar.po".

A similar problem was described here:
http://grokbase.com/topic/2006/08/07/xapian-discuss-search-with-symbols-causes-search-time-to-hemorrhage/oO3ndMNfB_B9PY-NntCHJT9STto
But I couldn't follow the link to the bug database
(http://www.xapian.org/cgi-bin/bugzilla/show_bug.cgi?id=22), since bugzilla
seems to be unavailable at the moment.

My question: is there any way to protect special characters in a query?

thanks for your time,
Lars

Turns out the guy who should be able to give me access to this is on
holiday, but didn't bother mentioning this to most people. I've got
someone checking to see if the old server is still powered; if not,
I'll go and collect it next week and power it from home. If it is, we
should be able to pull files off it in place, again probably early
next week.

Briefly: you probably need to avoid both TermGenerator and
QueryParser, and roll your own to get complete control over how you
generate terms out of document and query text. Queries themselves
don't care how you construct the terms.

ok - so I was just too much focused on the QueryParser.
Thanks for your help - it works now!

Re: UTF-8 Corruption

This is really good stuff. Many thanks for all your help Olly. I hope  
all goes well in NZ.

I put a copy of the 1.0.5 files I found in my apt-cache here if anyone  
needs them

I ordered a USB external SATA disk housing yesterday, which arrived just
now.  I've successfully copied off the 1.0.5 packages and uploaded them
to the new server.

I have a feeling there was a symlink or two that needed adding, but I
don't recall the details.  If you have a problem, please let me know
and I'll try to fix it.

I don't think I have the RPMs or omega templates though.  Fabrice/Tim:
if you have them still, let me know.  Otherwise they should reappear
early next week.

I now have the GPG key used to sign the archive too, so should be able
to sort out 1.0.6 packages fairly soon.

Cheers,
    Olly
