distributed query result order tie break question

[Michael Sokolov]

My question is about how query results are ordered in a distributed 
query when sorting by "relevance" and all the documents have the same 
score, for example, when querying for "*:*".

It looks to me as if score ties are broken by shard and then within each 
shard, by docid.  So for example, if I were to iterate over all the 
documents using such a query, I would expect to get all the documents 
from one shard first, then all the documents from another shard, etc.  
Is that right?

Thanks
