Nguyen Kien Trung updated SOLR-2242: ------------------------------------ Attachment: SOLR-2242.solr3.1-fix.patch I'm using Solr 3.2. Instead of patching, I extend {{SimpleFacets}} and {{FacetComponent}}, apply the changes mentioned in [^SOLR-2242.solr3.1.patch] with a small fix ([^SOLR\-2242.solr3.1-fix.patch]). {code} int offset = params.getFieldInt(facetValue, FacetParams.FACET_OFFSET, 0); .... resCount.add("numTerms", counts.size() + offset); {code} as {{counts}} contains list of terms started from the given {{offset}} It accepts param {{facet.numTerms=true|false}} and produce the output {code} <lst name="facet_fields"> <lst name="color"> <int name="numTerms">124</int> <lst name="counts" /> <int name="red">4</int> <int name="blue">3</int> </lst> </lst> </lst> {code} Not yet tested with sharding > Get distinct count of names for a facet field > --------------------------------------------- > > Key: SOLR-2242 > URL: https://issues.apache.org/jira/browse/SOLR-2242 > Project: Solr > Issue Type: New Feature > Components: Response Writers > Affects Versions: 4.0 > Reporter: Bill Bell > Assignee: Simon Willnauer > Priority: Minor > Fix For: 4.0 > > Attachments: NumFacetTermsFacetsTest.java, > SOLR-2242-notworkingtest.patch, SOLR-2242.patch, SOLR-2242.patch, > SOLR-2242.shard.patch, SOLR-2242.shard.patch, > SOLR-2242.shard.withtests.patch, SOLR-2242.solr3.1-fix.patch, > SOLR-2242.solr3.1.patch, SOLR.2242.solr3.1.patch, SOLR.2242.v2.patch > > > When returning facet.field=<name of field> you will get a list of matches for > distinct values. This is normal behavior. This patch tells you how many > distinct values you have (# of rows). Use with limit=-1 and mincount=1. > The feature is called "namedistinct". Here is an example: > http://localhost:8983/solr/select?shards=localhost:8983/solr,localhost:7574/solr&indent=true&q=*:*&facet=true&facet.mincount=1&facet.numFacetTerms=2&facet.limit=-1&facet.field=price > http://localhost:8983/solr/select?shards=localhost:8983/solr,localhost:7574/solr&indent=true&q=*:*&facet=true&facet.mincount=1&facet.numFacetTerms=0&facet.limit=-1&facet.field=price > http://localhost:8983/solr/select?shards=localhost:8983/solr,localhost:7574/solr&indent=true&q=*:*&facet=true&facet.mincount=1&facet.numFacetTerms=1&facet.limit=-1&facet.field=price > This currently only works on facet.field. > {code} > <lst name="facet_fields"> > <lst name="price"> > <int name="numFacetTerms">14</int> > <int name="0.0">3</int><int name="11.5">1</int><int > name="19.95">1</int><int name="74.99">1</int><int name="92.0">1</int><int > name="179.99">1</int><int name="185.0">1</int><int name="279.95">1</int><int > name="329.95">1</int><int name="350.0">1</int><int name="399.0">1</int><int > name="479.95">1</int><int name="649.99">1</int><int name="2199.0">1</int> > </lst> > </lst> > {code} > Several people use this to get the group.field count (the # of groups). -- This message is automatically generated by JIRA.
