Xapian discuss - Jan 2009 - 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 .
