Paul Elschot commented on LUCENE-7434:
--------------------------------------
As it happens I am in slow progress making something for the case
minNumberShouldMatch=2, all pairs.
In case there is interest in an early version of that, please let me know.
For the maximum window there will be similar restrictions as for LUCENE-7398.
> Add minNumberShouldMatch parameter to SpanNearQuery

> Key: LUCENE-7434
> URL: https://issues.apache.org/jira/browse/LUCENE-7434
> Project: Lucene - Core
> Issue Type: Improvement
> Components: core/search
> Reporter: Tim Allison
> Priority: Minor
>
> 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.
