------------------------------------------------------------------

attaching [^TestMinShouldMatchSpan.java] my attempt with [TermAutomationQuery|http://blog.mikemccandless.com/2014/08/a-new-proximity-query-for-lucene-using.html].
This test matches 3 of "a b c d" words as a phrase eg. it matches docs
{quote}
c *a* *b* *d*
*a* *b* *d* a
{quote}
also, it builds nice graphs like [^a b c d e f mm=3.PNG]. Beware %100 finite state pom inside!
Opinions ?

> 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.
