[Xapian-discuss] Xapian 1.0.7-3.1 (python libs) : can't find anything

[Cedric Jeanneret]

Hello,

I have a "little" problem : my xapian search engine cannot find anything. I explain:
here at office we have a fileserver with about 250G of files (pdf, odt, doc, txt,...) which are daily indexed with omindex. That part works fine.
Then, I've written a small app with pylons, using xapian python library. It worked some days, and now, it just cannot find anything unless we put a wildcart inside the word.... that's not really userfriendly.

Here's how I index my fileserver :
omindex -D <path-to-indexes>/indexes/commun -U http://some-url/ --stemmer=french /path-to-files/commun

and here's a sample of how I search through it :

def SearchXapian(qp, db, strq, nbres, page):
  strq = strq.encode('utf-8')

  database = xapian.Database()
  for i in db:
    d = xapian.Database(i)
    database.add_database(d)
  
  enquire = xapian.Enquire(database)
  
  qp.set_database(database)
  query = qp.parse_query(strq)
  enquire.set_query(query)
  
  matches = enquire.get_mset(int(page)*int(nbres), int(nbres))

qp : xapian.QueryParser, without any option (I tried with french stemmer, but no difference)
db : a list of my dbs (we can search through 3 indexes. this list contain path to activated indexes)
strq : query string (withour any modifications)
nbres : results per page (used for a pagination, later in the code, useless in here), default 10
page : used for paginate, default 0.


When I only print matches.get_matches_estimated(), it returns always 0... and when I tried with a "*" inside my word, it works more or less...

Any clue, idea?

If you need some more code, please ask me.

Regards,

C. Jeanneret
