facet.method=fc builds a multi-valued fieldcache like structure (UnInvertedField) the first time, that is used for counting facets for all subsequent requests. So the faceting time (after the first time) is O(ndocs of the set), but the UnInvertedField singleton uses a large amout of memory unrelated to any particular base docset. -Yonik http://www.lucenerevolution.org -- Lucene/Solr User Conference, May 25-26, San Francisco > Thanks > On Thursday, April 21, 2011, Yonik Seeley <yo...@lucidimagination.com> wrote: >> On Thu, Apr 21, 2011 at 11:15 AM, Ofer Fort <o...@tra.cx> wrote: >>> So if i want to use the facet.method=fc, is there a way to speed it up? and >>> remove the bucket size limitation? >> >> Not really - else we would have done it already ;-) >> We don't really have great methods for faceting on full-text fields >> (as opposed to shorter meta-data fields) today. >> >> -Yonik >> http://www.lucenerevolution.org -- Lucene/Solr User Conference, May >> 25-26, San Francisco >> >
