Hi Bratislav,
LUCENE-4517 sounds like what you want:
<https://issues.apache.org/jira/browse/LUCENE-4517>: "Suggesters: allow to pass
a user-defined predicate/filter to the completion searcher"
There's a patch there, against Lucene trunk from about 5 months ago, so if you
want to give it a try you'll have to figure out what Subversion revision that
was, check it out, apply the patch, then compile.
