             Summary: Add boosting support in the SynonymQuery
                 Key: LUCENE-8652
                 URL: https://issues.apache.org/jira/browse/LUCENE-8652
             Project: Lucene - Core
          Issue Type: Bug
            Reporter: Jim Ferenczi

The SynonymQuery tries to score multiple terms as if you had indexed them as 
one term.
This is good for "true" synonyms where each term should have the same 
contribution to the final score but this doesn't handle the case where terms 
have different weights. For scoring purpose it would be nice to be able to 
assign a boost per term that we could multiply with the term's document 
frequency in order to take into account the importance of the term within the 
synonym list.
