Subject [jira] [Commented] (LUCENE-7434) Add minNumberShouldMatch parameter to SpanNearQuery
Date Thu, 01 Sep 2016 19:40:20 GMT

Mikhail Khludnev commented on LUCENE-7434:
------------------------------------------

But this allow to create Span Disjunction Query, which is considered as a black sheep in Lucene
herd. I don't know why exactly, but have an idea.

> 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.
