Andy Webb created SOLR-13751:
--------------------------------
Summary: Add BooleanSimilarityFactory to Solr
Key: SOLR-13751
URL: https://issues.apache.org/jira/browse/SOLR-13751
Project: Solr
Issue Type: New Feature
Security Level: Public (Default Security Level. Issues are Public)
Reporter: Andy Webb
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/andywebb1975/lucene-solr/pull/1] (I'm
at the pre-Activate Hack Day in Washington DC.)
