Xapian discuss - Apr 2008 - Using special characters in query terms

Hi,

I would like to search for filenames in a xapian database.

For now my query for "foo-bar.po" turns into the following:
  Xapian::Query((foo:(pos=1) PHRASE 3 bar:(pos=2) PHRASE 3 po:(pos=3)))

This query is successful, if I used the term generator to tokenize
"foo-bar.po"
during indexing.

The problem is: this workaround makes it impossible to distinguish between
"foo-bar.po" and "foo/bar.po".

A similar problem was described here:
http://grokbase.com/topic/2006/08/07/xapian-discuss-search-with-symbols-causes-search-time-to-hemorrhage/oO3ndMNfB_B9PY-NntCHJT9STto
But I couldn't follow the link to the bug database
(http://www.xapian.org/cgi-bin/bugzilla/show_bug.cgi?id=22), since bugzilla
seems to be unavailable at the moment.


My question: is there any way to protect special characters in a query?


thanks for your time,
Lars

Briefly: you probably need to avoid both TermGenerator and
QueryParser, and roll your own to get complete control over how you
generate terms out of document and query text. Queries themselves
don't care how you construct the terms.
