Hi Shamik,

I'm not sure if this will help, but we built a plugin for 'XJoin', 
allowing you to use results from an external system with Solr. Here are 
two blog posts about it:
http://www.flax.co.uk/blog/2016/01/25/xjoin-solr-part-1-filtering-using-price-discount-data/
http://www.flax.co.uk/blog/2016/01/29/xjoin-solr-part-2-click-example/

Cheers

Charlie

Charlie, this looks something very close to what I'm looking for. Just
wondering if you've made this available as a jar or can be build from
source? Our Solr distribution is not built from source, I can only use an
external jar. I'll appreciate if you can let me know.

This type of ranking behavior is what the RankQuery is designed to do. A
RankQuery allows you to inject your own TopDocs collector into the query
and take full control of the ranking. It's more complex to implement
though. Here is an example RankQuery implementation:

https://github.com/apache/lucene-solr/blob/master/solr/core/src/java/org/apache/solr/search/ReRankQParserPlugin.java

And the base class this extends:

https://github.com/apache/lucene-solr/blob/master/solr/core/src/java/org/apache/solr/search/AbstractReRankQuery.java

I was going to say what Charlie said! I would trust Flax's work in this
area :)

Charlie, thanks for sharing the information. I'm going to take a look and get
back to you.
