different result for 'OR'
I would expect that the query *q=description:(electronics) or
description:(usb)* would give the same number of results as
*q=description:(electronics or usb)*. But the first query returns 9662
documents and the second one 9493. What is the difference?

OR should be in all caps there.

nevertheless it`s a Lucene-Bug
(there should be no difference in handling or / OR)

Thats it. I could have known it if I had read the documentation more
carefully. Replacing the 'or' by 'OR' does the trick.

That is odd. Can you print the Query.toString of the actual two
queries you are running? (I think the OR must be capitalized to be
parsed by the classic QueryParser?).
