[jira] [Commented] (LUCENE-3320) Explore Proximity Scoring

I think this will bring great improvement especially for long queries or natural language queries. I'd need proximity scoring for a project I'm currently working on... will give it a try. > Explore Proximity Scoring > -- > > Key: LUCENE-3320 > URL: https://issues.apache.org/jira/browse/LUCENE-3320 > Project: Lucene - Core > Issue Type: Sub-task > Components: core/search >Affects Versions: Positions Branch >Reporter: Simon Willnauer >Priority: Major > Fix For: Positions Branch > > > Positions will be first class citizens rather sooner than later.

Here is another paper that explores how one might fold positions into BM25 through "virtual regions" that are field-like: [https://www.dc.fi.udc.es/~roi/publications/sigir2012a.pdf] Not sure how it compares to the above paper! > Explore Proximity Scoring > -- > > Key: LUCENE-3320 > URL: https://issues.apache.org/jira/browse/LUCENE-3320 > Project: Lucene - Core > Issue Type: Sub-task > Components: core/search >Affects Versions: Positions Branch >Reporter: Simon Willnauer >Priority: Major > Fix For: Positions Branch > > > Positions will be first class citizens rather sooner than later.

LUCENE-2878 has been resolved a few years ago; is there possibility to proceed this issue, or is there someone who is already involved?
