LSH/MinHash

[Andy Hind <An...@oracle.com>]

Hi All

Following on from https://issues.apache.org/jira/browse/LUCENE-6968 <https://issues.apache.org/jira/browse/LUCENE-6968> (I know it’s been a while…)
I have a QParser plugin that can generate the appropriate banded queries for Jaccard similarity.

It covers the same functionality that was proposed in the original issue but wrapped up as a query parser.
There are two analysis cases and two query cases.. Hashes generated by tokenisation or those generated by pre-analysis. Queries based on text or provided hash values.

If there is interest, I will create the issue and put up the patch.

Regards

Andy

Hi Andy,

It would be very nice if you could do that and I'd be very interested
in reviewing and helping out with the patch.
I have been using that filter for a while with my own query bits; a
full fledged query parser would surely be a very useful contribution.

Regards,
Tommaso
