ES query returning unusual results

I have an ES cluster running ES 1.0.1 on 10 nodes, where an index is has 5
shards each with 1 replica.

Doing the following query kept alternately returning two distinct result
counts, say 103799 and 104430. I've since carefully removed 5 nodes from my
cluster and now for the same query I'm getting the same value consistently.
Anyone any idea what might have been going on? Unfortunately I can't
reproduce the behaviour any longer.

Regards,
Al.

If indexing was live/active, it probably was just your replicas not caught
up to the primaries for split seconds.
