-------------------------------------
Summary: Add support for minShouldMatch and tolerateOtherTerms in
{!terms} TermsQParserPlugin
Key: SOLR-16004
URL: https://issues.apache.org/jira/browse/SOLR-16004
Project: Solr
Issue Type: Improvement
Security Level: Public (Default Security Level. Issues are Public)
Components: query parsers
Affects Versions: main (10.0)
Reporter: Michael Gibney
In Solr, the TermsQParser considers a match if _any_ term in a doc/field
matches. It can be useful in some contexts (e.g., access control, etc.) to
require that a certain threshold of terms match, or to require exclusive
presence of enumerated terms (i.e., place a limit on the number of terms that
exist in a document that have _not_ been explicitly enumerated in the query).
As a point of comparison, Elasticsearch implements the former feature as the
[minimum_should_match_field
param|https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-terms-set-query.html#terms-set-field-params]
on its "Terms set query" (the latter feature -- exclusive presence -- is
afaict not implemented).
