Tomás Fernández Löbbe commented on SOLR-6216: --------------------------------------------- I have been testing this code in 4.x too, it works fine too. The tests need to omit "Lucene3x" codec in addition to the omitted in trunk > Better faceting for multiple intervals on DV fields > --------------------------------------------------- > > Key: SOLR-6216 > URL: https://issues.apache.org/jira/browse/SOLR-6216 > Project: Solr > Issue Type: Improvement > Reporter: Tomás Fernández Löbbe > Attachments: SOLR-6216.patch, SOLR-6216.patch, SOLR-6216.patch, > SOLR-6216.patch, SOLR-6216.patch, SOLR-6216.patch > > > There are two ways to have faceting on values ranges in Solr right now: > “Range Faceting” and “Query Faceting” (doing range queries). They both end up > doing something similar: > {code:java} > searcher.numDocs(rangeQ , docs) > {code} > The good thing about this implementation is that it can benefit from caching. > The bad thing is that it may be slow with cold caches, and that there will be > a query for each of the ranges. > A different implementation would be one that works similar to regular field > faceting, using doc values and validating ranges for each value of the > matching documents. This implementation would sometimes be faster than Range > Faceting / Query Faceting, specially on cases where caches are not very > effective, like on a high update rate, or where ranges change frequently. > Functionally, the result should be exactly the same as the one obtained by > doing a facet query for every interval -- This message was sent by Atlassian JIRA (v6.2#6252) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
