Hello all,
Let`s have an indexed text "Test (1) and test (2)".
Now search for: \(1\)
Everything OK, so lets search for: \(?\)
Nothing found! It`s same with \" and maybe other escaped characters.
Is this a bug? Is it already solved in the CVS? If not, how can we fix
it?
Thanks for help! Lucene rocks.
ps - have anybody compiled lucene with GCJ? if so with any results in
performance?
attaching JUnit test....
