Changing maxBooleanClauses doesn't make any difference at all. Having
thousands of clauses is what makes things run slower and take more memory.
The setting just causes large queries to fail without running. If you need
a query with more than 1024 clauses and there's no other way to do the
job, then you have to increase it.
