[hibernate-dev] HSEARCH State to transfer

HSEARCH-681 HSEARCH-757 I've done a first analysis for the state to transfer. It's not too bad. This doc is cryptic but people familiar with Lucene should get what I mean: https://gist.github.com/1120651 It describes the state to pass around for each operation and detail what Document and Fieldable contain state wise and what would be transferred. The two big annoyances are: - Reader - TokenStream both of them can be the source of a Field. While we can envision some strategies for Reader (worse case being we read the data and ship it over). I have not yet analyzed the implications of TokenStream. For the rest with a smart enough state machine and possibly some private attribute reading, we should be able to serialize / deserialize Documents and Fieldables Emmanuel
