Hello,
Currently we are facing the problem that some searches espacially fuzzy
(term~0.6) wildcard searches (*term*) needs some time depending on the
field-searchword combination (the more terms there are the more processing has
to be done).
We improved the performance through caching the bitsets of the single fuzzy
query/wildcard query.
Within our logs we can see that combined queries within a BooleanQuery are
processed sequentially. So our question are: Does it make sense for you to
parallelize the processing of the queries within a boolean query (with a
restriction of the amount of prallel processed queries)? With the caches in
mind it might be faster and the system is running on a multicore machine. Has
anyone experience in prallelizing single query processing within a BooleanQuery?
Could there be drawbacks combining the results of the booelan clauses (e.g some
IO). At the end there should only be the bitsets connected to the terms and
this should be in memory already, shouldn't it?
Thanks in advance
stephan
