The query you're running would help. But here's a guess: You say you have a "3 node Solr cluster". By that I'm guessing you mean a single shard with 1 leader and 2 replicas.
when the primary sort criteria (score by default) is tied between two documents, the internal Lucene doc ID is used as a tiebreaker. If you're doing something like a *:* query (asterisk:asterisk in case bolding happens) then the score for all docs is the same. Here's the kicker: the internal Lucene doc id will be different in each replica. So my guess is you're getting results from different replicas where the internal doc id is between docs has different relations. So I claim you don't get different results every time, you get 1 of three result orderings at a guess. If you have a decent size corpus and are searching by more interesting criteria this should be much less of a problem, but still theoretically can happen. To nail down the ordering completely, specify a secondary sort, as &sort=score,id Best, Erick On Thu, Jul 23, 2015 at 8:46 AM, Tarala, Magesh <mtar...@bh.com> wrote: > I have about 15K documents in a 3 node solr cluster.
