Toke Eskildsen commented on SOLR-2412: -------------------------------------- If the README in solr/contrib/exposed/ does not help, I will be happy to answer any questions and try to explain it better. > Multipath hierarchical faceting > ------------------------------- > > Key: SOLR-2412 > URL: https://issues.apache.org/jira/browse/SOLR-2412 > Project: Solr > Issue Type: New Feature > Components: SearchComponents - other > Affects Versions: 4.0 > Environment: Fast IO when huge hierarchies are used > Reporter: Toke Eskildsen > Labels: contrib, patch > Attachments: SOLR-2412.patch, SOLR-2412.patch, SOLR-2412.patch, > SOLR-2412.patch, SOLR-2412.patch, SOLR-2412.patch, SOLR-2412.patch > > > Hierarchical faceting with slow startup, low memory overhead and fast > response. Distinguishing features as compared to SOLR-64 and SOLR-792 are > * Multiple paths per document > * Query-time analysis of the facet-field; no special requirements for > indexing besides retaining separator characters in the terms used for faceting > * Optional custom sorting of tag values > * Recursive counting of references to tags at all levels of the output > This is a shell around LUCENE-2369, making it work with the Solr API. The > underlying principle is to reference terms by their ordinals and create an > index wide documents to tags map, augmented with a compressed representation > of hierarchical levels. -- 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
