Subject [jira] [Created] (SOLR-9888) Add a boosting dismax query parser (bmax)
Date Thu, 22 Dec 2016 10:17:58 GMT
Tobias Kässmann created SOLR-9888:

             Summary: Add a boosting dismax query parser (bmax)
                 Key: SOLR-9888
             Project: Solr
          Issue Type: Improvement
      Security Level: Public (Default Security Level. Issues are Public)
            Reporter: Tobias Kässmann
            Priority: Minor

We've created the bmax parser that is in production for about 2 years because the provided
ones did not fit our requirements any more. The bmax query parser relies on field types and
tokenizer chains to parse the user query, discover synonyms, boost and penalize terms at query
time. Hence it is highly configurable. The lucene query composed is a boosted and reranked
dismax query with a minimum must match of 100%.

All sources and documentation is currently available here:

If this is query parser is interesting for Solr, we will create a pull request.
