Robert Muir commented on LUCENE-2662:
-------------------------------------

Jason: I am confused... there is no hash impl in TermsHashPerField.

the hashing, and term encoding and other things, is the responsibility of the 
analysis chain (TermToBytesRefAttribute):
{code}
    // Get the text & hash of this term.
    int code = termAtt.toBytesRef(utf8);
{code}

this way, implementations can 'hash-as-they-go' like we do when encoding 
unicode char[] -> byte[],
or they can simply return BytesRef.hashCode() if they don't have an optimized 
implementation.
