Terms set query in Elasticsearch

Terms set query returns document depending on minimal number of exact terms matching into given field.

The only difference between Terms set query and Terms query is that you can provide the minimal number of terms that must match in order to retrieve certain document.

A document’s numeric field name whose value should be used as the required minimum number of terms to match in order to return the document.

A custom script that determines the minimum number of terms that must match in order to return the documents. If you have to dynamically set the number of terms that are required for match then it will be helpful.
