Michael McCandless commented on LUCENE-4600: -------------------------------------------- bq. Can you compare it to Counting directly? Ugh, sorry, that is in fact what I ran but I put the wrong base/comp above it. The test was actually base = PostCollectionCountingFacetsCollector, comp = CountingFacetsCollector. > Explore facets aggregation during documents collection > ------------------------------------------------------ > > Key: LUCENE-4600 > URL: https://issues.apache.org/jira/browse/LUCENE-4600 > Project: Lucene - Core > Issue Type: Improvement > Components: modules/facet > Reporter: Michael McCandless > Attachments: LUCENE-4600-cli.patch, LUCENE-4600.patch, > LUCENE-4600.patch, LUCENE-4600.patch, LUCENE-4600.patch, LUCENE-4600.patch, > LUCENE-4600.patch > > > Today the facet module simply gathers all hits (as a bitset, optionally with > a float[] to hold scores as well, if you will aggregate them) during > collection, and then at the end when you call getFacetsResults(), it makes a > 2nd pass over all those hits doing the actual aggregation. > We should investigate just aggregating as we collect instead, so we don't > have to tie up transient RAM (fairly small for the bit set but possibly big > for the float[]). -- This message is automatically generated by JIRA.
