> Key: SOLR-12879
> URL: https://issues.apache.org/jira/browse/SOLR-12879
> Project: Solr
> Issue Type: New Feature
> Security Level: Public(Default Security Level. Issues are Public)
> Components: query parsers
> Affects Versions: master (8.0)
> Reporter: Andy Hind
> Assignee: Tommaso Teofili
> Priority: Major
> Fix For: master (8.0)
>
> Attachments: minhash.filter.adoc.fragment, minhash.patch
>
>
> 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.
