[Xapian-discuss] Omega and Wildcards

[Kenneth Loafman]

I made the following changes to Omega, per the instructions in

http://www.xapian.org/docs/queryparser.html,

and wildcards do not work at all.  I'm hoping its something simple.

/usr/lib/cgi-bin/omega/omega DB=pdf P=finan\*
(with or without the backslash)

returns no documents, even though there are over 3000 hits for
'finance', about the same for 'financial', and probably more.
