Allows the records (rids) retrieved from the Lucene search to be limited, where it is known that the remainder of the query does not require the entire set to be loaded.
This is useful when the underlying Lucene query returns many results, but the query overall is only intended to return a small number of them (usually in the ranked order from Lucene).
This mode is opt in, by providing a "limit" metadata element to the Lucene search function. A value of "select' uses the skip/limit in the SELECT statement to determine the max hits, and an integral value specifies an explicit max hits (e.g. for a safety margin).
