Subject [jira] [Updated] (SOLR-2242) Get distinct count of names for a facet field
Date Sun, 11 Nov 2012 22:33:13 GMT

     [ https://issues.apache.org/jira/browse/SOLR-2242?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Bill Bell updated SOLR-2242:
----------------------------

    Description: 
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:

Parameters:
facet.numTerms or f.<field>.facet.numTerms = true (default is false) - turn on distinct
counting of terms

facet.field - the field to count the terms
It creates a new section in the facet section...

http://localhost:8983/solr/select?shards=localhost:8983/solr,localhost:7574/solr&indent=true&q=*:*&facet=true&facet.mincount=1&facet.numTerms=true&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.numTerms=false&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.numTerms=true&facet.limit=-1&facet.field=price

This currently only works on facet.field.

{code}

<lst name="facet_counts">
<lst name="facet_queries"/>
<lst name="facet_fields">...</lst>
<lst name="facet_numTerms">
<lst name="localhost:8983/solr/">
<int name="price">14</int>
</lst>
<lst name="localhost:8080/solr/">
<int name="price">14</int>
</lst>
</lst>
<lst name="facet_dates"/>
<lst name="facet_ranges"/>
</lst>

OR with no sharding-

<lst name="facet_numTerms">
<int name="price">14</int>
</lst>

{code} 

Several people use this to get the group.field count (the # of groups).
