A Document, when reconstituted from Hits, is essentially a glorified
HashMap-like structure. I recommend you simply iterate your HashMap
during indexing and add each entry to the Document as a Field.Keyword
or as an unindexed field. It may be slightly more code than doing
some type of serialization/de-serialization, but not by much.

Subject: Storing HashMap as an UnIndexed Field
Hi,
I'd like to store a HashMap for some extra data to be used when a
given document is retrieved as a Hit for a query. To add an
UnIndexed
Field to an index takes only Strings as parameters. Does anyone have
any suggestions on how I might convert the HashMap to a String
that is
efficiently recomposed into the desired HashMap on the other end?
Thanks,
Tricia
