Description

A search request which looks up a doc with just a uniqueKey can be optimised to lookup the right shard and send a distrib=false request and avoid the overhead of a distributed request.

The same can also be achieved by the /get handler but it has the (admittedly small) overhead of looking up from the transaction log as well.
