Solr 1.3: If I am only getting back the document ids from a distributed search (e.g., uniqueid is 'id' and the fl parameter only contains 'id'), there seems to be some room for optimization in the current code path:
1) On each shard, grab top N sorted document ids & sort fields) 2) Merge these into one list of N sorted id fields. 3) Query each shard for the details of these documents (by id), getting back a field list of id only. It seems to me that step 3 is overhead that can be skipped. Any thoughts on this/known patches? Thanks, -Joe
