No, it means that the idf calculation is done locally on a single shard. With a big index that is randomly mixed, this should not have a practical impact. > 2) Doesn't support consistency between stages, e.g. a shard index can be > changed between STAGE_EXECUTE_QUERY and STAGE_GET_FIELDS > > What does this mean or where can I find out what it means? STAGE_EXECUTE_QUERY finds the ids of matching documents. STAGE_GET_FIELDS retrieves the fields of matching documents. A change to a document could possibly happen inbetween, and one would end up retrieving a document that no longer matched the query. In practice, this is rarely an issue. -Yonik
