Joe Shaw updated LUCENENET-11:
------------------------------
Attachment: 11_charstream-no-exceptions.patch
I just noticed that we've had a similar patch in our tree (for Beagle) for
quite some time and have been using it for over a year. It only addresses the
FastCharStream in the StandardAnalyzer, but it should be easy to apply it to
the QueryParser as well.
> Avoiding non necessary exceptions

> As already said in previous issues, there are few exceptions that are raised
> for no reason (apparently).
> I updated FastCharStream, QueryParserTokenManager, FieldInfos to avoid these
> kind of exception.
> - FastCharStream.ReadChar() returns '\0' if we are trying to read byond the
> end of the stream.
> - Updated QueryParserTokenManager to support the previous fix
> - Update FieldInfos.FieldName. No more reading take place if fieldNumber is
> -1.
