Minor Description
Please add a mechanism that makes querying by rowid less taxing on the shard servers. Rowid is not something that I want to put in block cache, but it is a field that is convenient to use in queries.
Currently in queries, rowid acts like any other field, so all shard servers that do not have the rowid in question have to parse the query and run the search even though they are guaranteed to not produce any results.
It would be nice if this behavior could be short circuited when rowid is a required query element and is a full string (doesn't include wildcards or ranges of any sort).
