Requested size is 1 for the query, but when the query is run on all the 8 shards it returns 8 records

Hi,

This post is related to the below one.
https://groups.google.com/d/topic/elasticsearch/jJnOcAVP_L4/discussion

The query has a from:"0" and size:"1", but this query gets 1 record from
each of the 8 shards on the index and the java API displays 8 records. I'm
not sure if this is some configuration issue.

Thanks,
John

Did you change your search type to query_and_fetch? With query_and_fetch,
you will get n results from each shard, where n is the size requested.
Default search type is query_then_fetch.

It's hard to follow you in what your curl line looks like, so it's hard
to comment. In Java API you use DFS query then fetch. So I think you
also used in curl the parameter search_type= dfs_query_then_fetch. Also,
you used setExplain(true) in Java which means, curl should have run
through the _explain endpoint. But I am not sure.
I suggest you respect both parameters (explain and search_type) and
then, result size should be the same.

Jörg, the code had been changed from the "DFS query then fetch" or "query
then fetch" to "query and fetch" by someone. Sorry about the confusion i
caused.
