Sebastian Steinmetz commented on NUTCH-479:
-------------------------------------------

I've integrated this patch against 0.9 and it seems to have some problems. I'm not sure, if I should have tested it against trunk.

The problem is the parsing itself. If I enter "foo OR bar" (without qotes) it gets reformed to a Lucene query which reads like: "+foo bar" but it should be "foo bar" i think...
At least is the result, if I change it in debug mode by hand to "foo bar", the pages that I would expect to appear.

I don't have any idea, how to fix this yet. But if I have one, I'll let you know...
