patch commited ... i'll update work on some better wiki pages this afternoon. > Basic Facet Count support > ------------------------- > > Key: SOLR-44 > URL: http://issues.apache.org/jira/browse/SOLR-44 > Project: Solr > Issue Type: New Feature > Components: search > Reporter: Hoss Man > Assigned To: Hoss Man > Attachments: simple-facets.patch, simple-facets.patch, > simple-facets.patch, simple-facets.patch > > > First pass at basic facet support. initial patch includes utilities for use > in RequestHandlers, and usage in StandardRequestHandler (DisMax should use > SolrParams before attempting to add this) > Basic idea is that: > * facet=true indicates facet counts are desired. > * facetField=inStock indicates we want a count of the matching docs for > each value in the field inStock > * facetQuery=title:ipod indicates we want the count of matching docs also > in the set of docs matching query title:ipod > * if user wants to apply a facet constraint on subsequent queries, they can > add an "fq" (filter query) param (support for this was added to > StandardRequestHandler as well) > Things marked TODO... > * add support for per field facetLimit indicating that only the top N items > in each facetField should be returned > * add support for a per field facetZero boolean indicating that there is no > reason to bother returning counts of 0 for facetFields (some clients may want > to know the list, others don't care) > * potential optimization when using faceLimit to cache the terms with the > highest docFreq and see if they provide all the info we need without doing a > full TermEnum > I'd like to get some feedback on the overall appraoch and params before i > proceed too much farther. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://issues.apache.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
