             Summary: Should we switch BytesRefHash to MurmurHash3?
                 Key: LUCENE-5604
                 URL: https://issues.apache.org/jira/browse/LUCENE-5604
             Project: Lucene - Core
          Issue Type: Improvement
          Components: core/index
            Reporter: Michael McCandless
            Assignee: Michael McCandless
             Fix For: 4.9, 5.0


MurmurHash3 has better hashing distribution than the current hash function we 
use for BytesRefHash which is a simple multiplicative function with 31 
multiplier (same as Java's String.hashCode, but applied to bytes not chars).  
Maybe we should switch ...
