Empty results beyond 10 pages with rescore query

[parthibane]

Hi,

we've recently implemented rescore to rank docs, I'm getting empty results when I go beyond 10 pages. if I remove rescore from my DSL query it's returning results. So something happening when paginating with rescore.

For example, let say my search DSL query has "size" is 1 and "from" is 0. It's returning results until "from" is 10, beyond 10 it's returning empty results.

Elasticsearch version : 1.5.2

Please check this issue.

My sample DSL query for 11th page

{
"_source": ["name","id" ],
"query": {
"query_string": {
"query": "any keyword",
"fields": ["_all"]
}
},
"from": 11,
"rescore": {
"query": {
"rescore_query": {
"function_score": {
"script_score": {
"script":"[my script]",
"lang": "groovy"
}
}
},
"score_mode": "multiply"
},
"window_size": 300
}, "size": 1
}

Sample result for 11th page

{
"took": 21,
"timed_out": false,
"_shards": {
"total": 11,
"successful": 11,
"failed": 0
},
"hits": {
"total": 14021,
"max_score": 1,
"hits": [ ]
}
}

You are going to have more luck if you can post a curl recreation.
