It is (relatively ) slow because I send very large boolean queries. This may differ from the general use of Lucene where people search for a few terms and want to access only the n first documents. Profiling my apps shows that Term access and creation consumes a lot of time. There was a discussion about this issue when Dmitry proposed a patch to limit creation of temporary Term objects. In my case this is even more obvious because of the size of the queries.
