Possible Bug when add wildcard to search following an exclamation
mark
If I do a search which consists of escaped ending exclamation marks it
all works okay:
(aaaaahhh\!\!\!)
and find the desired match
but if there is a wildcard at the end, it will not find any matches
(aaaaahhh\!\!\!*)
I cant see Im doing anything in my code that would affect this, is this
a bug in lucene ?
thanks Paul

Quite a lot said in that issue, it seems to be concentrating on escaping
wildcards chars (?, *), whereas I'm escaping an !, as part of a wildcard
query. But I'll assume this issue covers that
Thanks alot Paul

wildcards don't support escaped characters, but will in 4.0

What analyzer are you using? Same at indexing and search time? What
version of lucene? What does Luke show as being indexed?
