Shai Erera updated LUCENE-4838:
-------------------------------
Attachment: LUCENE-4838.patch
Renamed to find and replaced all mentions of 'ord' and 'ordinal' by 'id' and
'bytesID' (depending on context).
Simon, I couldn't use find() in add() because the lookup code modifies the
hashcode given to the method, which is later used to add the new entry. So
find() needs to return two values (the id and modified hashcode), which
unfortunately we can't do. Anyway, this is not such a long code.
I think it's ready.
> Add getOrd to BytesRefHash

> 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.
