Date Sat, 16 Mar 2013 08:24:12 GMT


Shai Erera updated LUCENE-4838:

    Attachment: LUCENE-4838.patch

Patch adds getOrd(BytesRef) with and without pre-computed hash code + matching test in TestBytesRefHash.
If there are no objections, I will commit it later.

> There is no API today to query BytesRefHash for the existence of a certain BytesRef.
Rather, you should use .add(), which looks up the given bytes, and hashes them if they are
not found, or returns their ord if they are found.
> I would like to add a simple getOrd API which will return the ord of a given BytesRef,
or -1 if not found. I would like to use that API in the facet module, and I need to be able
to query the hash without necessarily adding elements to it.
> I have a simple patch, will post shortly.
