Subject [Lucene.Net] [jira] [Updated] (LUCENENET-415) Contrib/Faceted Search
Date Mon, 23 May 2011 15:25:47 GMT


Ben West updated LUCENENET-415:

    Attachment: facet performance.xls

I added an option to SFS which selects whether queries are cached. I think this cache is only
cleared on index reopen, so caching everything can be memory intensive (right?). Without this
caching, it seems that memory impact should be minimal.

Also attached some performance results, having made Digy's suggested changes.  Faceting is
somewhat slower, particularly on larger indexes, but is fine for my usage.

Interestingly enough, instantiation is almost instantaneous, which is good for those of us
on NRT.
