[Xapian-discuss] phraze recognition, intersection

[Lucian Nicolescu]

Thanks for the answer!
I partially solved the problem by doing some extra queries:
Using the input text I searched for a list of related postings. Then got the
most relevant result from the index using the input text and matched
postings in the relevant result against the ones in the related list. Took
out compositions of minimum 2 postings that were on consecutive positions.

This way I end up with a list of 2, sometimes 3 postings that actually make
sense and are related to the initial query (even if they are stemmed).
That is my solution in case anyone might be interested.

Btw: I read a couple of posts on highlighting the results of a query; from
what I can tell there is no solution, right? I am using Xapian with the
python bindings, not Omega.

Thanks,
Lucian Nicolescu
