Description

Following on from https://issues.apache.org/jira/browse/LUCENE-6968, provide a query parser that builds queries that provide a measure of Jaccard similarity. The initial patch includes banded queries that were also proposed on the original issue.

 

I have one outstanding questions:

• Should the score from the overall query be normalised?

Note, that the band count is currently approximate and may be one less than in practise.
