[jira] [Updated] (SOLR-13751) Add BooleanSimilarityFactory to Solr

     [ https://issues.apache.org/jira/browse/SOLR-13751?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Andy Webb updated SOLR-13751:
-----------------------------
    Description: 
Solr doesn't expose Lucene's BooleanSimilarity (ref LUCENE-5867) so it's not available for use in situations where BM25/TDF-IF are not useful.

Our use case is ngram-driven suggestions, where the frequency of occurrence of a particular sequence of characters is not something users would expect to be taken into account when ordering suggestions.

 

Here's my draft PR: [https://github.com/apache/lucene-solr/pull/867] (I'm at the pre-Activate Hack Day in Washington DC.)
