Bad results due to sharding!

Elastic Stack Elasticsearch
1

Hello

I have the default configuration of the elastic search node: 5 shards and 1
replica. I query the node which matches on particular field which is the
same for many documents in these 5 shards. However the search results have
different scores due to the tf-idf for that document in that particular
shard. Ideal scenario for me would be to have the same score for the
document for the same fields across different shards and I could break ties
by ordering on a second criteria which is important to me. How to
accomplish this?

Have a look at http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/search-request-search-type.html#dfs-query-and-fetch

It should help.
