Hello,
I'm overwriting getFacetInfo(...) method from standard request handler (BTW:
thanks for making a separate method for faceting :-))
What I need is to ran original query several times with filter query which I
generate based on result from original query. Bellow is part of my code.
I was thinking may be I could run those queries not one by one but in parallel,
in separate threads. But it appears that it takes longer than to run queries
one by one.
Do you have any idea why? Do you think the idea to run those queries in
separate threads is good in general? Are SolrIndexSearcher and SimpleFacets
thread safe?
Thank you
Gene
