Is there a built-in functionalities in solr/lucene to filter the results if they fall below a certain score threshold? Let's say if I provide a score threshold of .2, then all documents with score less than .2 will be removed from my results. My intuition is that this is possible by updating/customizing solr or lucene.
Could you point me to right direction on how to do this?
Thanks in advance!

You could write your own Collector that would ignore collecting those documents that the scorer places below your threshold. Below is a simple example of this using Lucene.Net 2.9.1.2 and C#. You'll need to modify the example if you want to keep the calculated score.
