Is the wiki down?

I'm getting the following:

  Oops…

Hi all,

Win32 Visual C++ build files are now available from the usual place:
http://lemurconsulting.com/Products/Xapian/Overview.shtml

You can now build the C# bindings using Microsoft tools.

Happy New Year!

Cheers

New example on wiki

I've added another bit of example code to the wiki.  This is a 
demonstration of using perl to parse text files, generate an input file 
for scriptindex using a half dozen or so fields and running 
scriptindex.  The program, index file and data are all available.  If 
anyone runs into any problems, please let me know and I'll try to help.  
I'm not a professional writer so it might be gibberish but I'm sure 
someone will tell me if so.

Thanks,
Jim.

Re: cygwin python binding build error

There are cygwin ports packages of Xapian - looking at them here I see
various patches are being applied, but nobody has told me about these
before so they aren't in the source code tarballs:

http://cygwin-ports.svn.sourceforge.net/viewvc/cygwin-ports/ports/trunk/libs/xapian-bindings/

I'll apply the fixes I actually understand shortly, but I don't follow
why all of them are needed - for example, why -module is dropped from
*_la_LDFLAGS (but not in all cases - e.g. for Ruby it is left in)?

Cheers,
    Olly

OK, now applied to SVN trunk (and these changes will get backported for
1.0.11 unless they prove problematic) apart from:

* removal of -module for some languages (as explained above).

* removal of "xapian.pyc xapian.pyo" from pylib_DATA (again, I don't
  understand this change - I wondered if it was Cygwin Ports packaging
  policy, but I didn't find any info about that online; if it is, it
  would be better done in xapian-bindings-1.0.10-1.cygport I think).

* I didn't apply the changes for libtool 2.2.x since once the other
  patches are merged, running autoreconf is presumably no longer
  required.

If any of these are actually required, I'd like to understand why before
applying them.

Contextual highlighting.

I know the subject has been discussed and there is a summary of 
discussions on the subject on the wiki.  A while back I was curious as 
to how the Search::Tools::HiLiter and Search::Tools::Snipper modules 
might work with Xapian so I generated a test.  I've cleaned up that test 
and decided to publish it.  A readme is located at 
http://fayettedigital.com/downloads/README.html.  The file can be 
downloade from http://fayettedigital.com/downloads/nsearch.tar.  It 
works OK on Ubuntu 8.04 and with difficulty on Centos 5.1. 

There is a lot of javascript included.  It uses AJAX to communicate with 
the perl CGI file.  It requires the dojo toolkit.

It's not fancy but if anyone is interested in toying with the previously 
mentioned modules, it's a starting point.  It includes a database, the 
same on that I described creating in my recent wiki article.

Jim.

Question about how Omega gets its data

I see in the xml output from omega the following:

<terms>
<term term="Ztest" show="tests"/>
<term term="Zwant" show="wanted"/>
</terms>

For each hit.  I know I can get the "terms" from the Enquire object via 
get_matching_terms_begin and get_matching_terms_end but where do the 
unstemmed values shown in the "show" keyword above come from?

Thanks,
Jim.

It uses a method on the QueryParser, unstem_begin(), which gives a
TermIterator over unstemmed terms *in the query* of the stemmed term
supplied. See
<http://xapian.org/docs/apidoc/html/classXapian_1_1QueryParser.html#bed4668a2ed42741c3c0cfc7eb7db2d8>,
and the ``pretty_term()`` method in Omega's query.cc .
