Summary: terms filter in json.facet
Key: SOLR-14921
URL: https://issues.apache.org/jira/browse/SOLR-14921
Project: Solr
Issue Type: Bug
Security Level: Public (Default Security Level. Issues are Public)
Components: Facet Module
Reporter: gopikannan venugopalsamy
Hi,
In normal facet request below can be used to filter the facet terms. I am not
able to do the same using json.facet. It would be useful in case of multivalued
field facet and only filtered terms needs to be returned.
h3. Limiting Facet with Certain Terms
To limit field facet with certain terms specify them comma separated with
{{terms}} local parameter. Commas and quotes in terms can be escaped with
backslash, as in {{\,}}. In this case facet is calculated on a way similar to
{{facet.method=enum}} , but ignores {{facet.enum.cache.minDf}}. For example:
{{facet.field=\{!terms='alfa,betta,with\,with\',with space'}symbol}}
{{}}
[https://lucene.apache.org/solr/guide/6_6/faceting.html]
Just like prefix parameter in json.facet I think we can add terms parameter and
use it. Something like below.
json.facet=\{facets:{type:terms,field:field1,terms:"a,b,c"}}
