------------------------------------
I just want to mention that I have also seen many questions and requests for
this feature on different elasticsearch forums. Here are a couple of examples
from stackoverflow :
-
http://stackoverflow.com/questions/31258959/elasticsearch-documents-that-only-have-terms-intersecting-a-list-of-terms-but-no
-
http://stackoverflow.com/questions/32580295/elasticsearch-match-all-words-from-document-in-the-search-query
It seems to me that there is a need for such functionality.
> Support boolean subset matching

> Key: LUCENE-7148
> URL: https://issues.apache.org/jira/browse/LUCENE-7148
> Project: Lucene - Core
> Issue Type: New Feature
> Components: core/search
> Affects Versions: 5.x
> Reporter: Otmar Caduff
> Labels: newbie
>
> In Lucene, I know of the possibility of Occur.SHOULD, Occur.MUST and the
> “minimum should match” setting on the boolean query.
> Now, when querying, I want to
> - (1) match the documents which either contain all the terms of the query
> (Occur.MUST for all terms would do that) or,
> - (2) if all terms for a given field of a document are a subset of the query
> terms, that document should match as well.
> Example:
> Document d hast field f with terms A, B, C
> Query with the following terms should match that document:
> A
> B
> A B
> A B C
> A B C D
> Query with the following terms should not match:
> D
> A B D
