ESCAPING BUG \(abc\) and \(a*c\) in v1.2

[Lukas Zapletal]

Hello all,

I posted Escaping bug earlier to this list and bugzilla, but it was rejected. I fixed the testing code, now it is created with same StandardAnalyzers and the problem is still there. Can anybody help me? Can anybody test it? Please help me it is important to me!

I`m also creating Bugzilla record too.

/**
* Escape bug (now with same analyzers). By [EMAIL PROTECTED]

* When searching for \(abc\) everything is ok. But let`s search for: \(a?c\)
* YES! Nothing found! It`s same with \" and maybe other escaped characters.
