> The bmax query parser is an extension to the edismax query parser. It does 
> some query preprocessing and does more comprehensive synonym lookup. It 
> distinguishes between directional synonyms as well as boost and penalize 
> terms. It 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: 
> https://github.com/shopping24/solr-bmax-queryparser
> If this is query parser is interesting for Solr, we will create a pull 
> request. The bmax parser has been running in production for about 2 years now 
> and is actively maintained.
