Subject [jira] [Commented] (LUCENE-7434) Add minNumberShouldMatch parameter to SpanNearQuery

Saar Carmi commented on LUCENE-7434:
------------------------------------

Thanks [~tallison@mitre.org] for creating this issue.

In order to merge threads, I want to clarify that my original question was about limiting
the search window as well as the number of matches.
The slop  parameter sets the maximum distance allowed between each of the subspans and I was
looking to add another parameter for the maximum window in which multiple the sub spans should
appear together - between the beginning of the first, to the beginning/end of the last one.

> On the user list, [~saar32] asked about a new type of SpanQuery that would allow for
something like BooleanQuery's minimumNumberShouldMatch
> bq. Given a set of search terms (t1, t2, t3, ti), return all documents where in a sequence
of x=10 tokens at least c=3 of the search terms appear within the sequence.
> I _think_ we can modify SpanNearQuery fairly easily to accommodate this.  I'll submit
a PR in the next few days.
