This is not the case.
maxClauseCount limit number of terms that can fit into BooleanQuery
during some queries rewriting. And default value is 1024, not 32.
32 required/prohibited clauses is limitation of Lucene 1.4.3 due to
usage of bit patterns to mask required/prohibited clauses.
You can solve this problem by using Lucene 1.9 RC or use Filters.

with this solution i get sometimes a "More than 32
required/prohibited clauses in query." Exception. Anyone a solution
for my that problem or some sites for me where i could look at (with
some examples)? Or is there a way to generate (relativly fast) a
subindex?
You can increase the limit from 32 to just about anything you want via
the system property org.apache.lucene.maxClauseCount. You can use
code like this:
System.setProperty"org.apache.lucene.maxClauseCount", "1000000");
Or, you can set a value on the JVM's command line with -D.
Good luck!
