There is no caching of queries done by htsearch itself, but you may be
seeing a speedup due to the OS's disk caching. Fuzzy matches won't of
themselves cause a whole lot more I/O, unless they cause a whole lot more
documents to be matched, which will lead to htsearch fetching a whole lot
more DocumentRef records from db.docdb.
