Doron Cohen commented on LUCENE-1028:
-------------------------------------

Thanks for catching this Kyle.
Patch looks good to me and working.
I enhanced checkQuery() in test/a.o.l.search.QueryUtils to check all queries for serialization.
This catches this bug and verifies the fix.
It also shows that BoostingTermQuery fails fr this check, but I am not sure why.

> In order to work with ParallelMultiSearcher, Query weights need to be serializable.  The interface Weight extends java.io.Serializable, but it appears that some of the newer queries unnecessarily store global state in their weights, thus causing serialization errors.
