Max_score is not coming for query with filter search


(bagui) #1

Hi,

I'm doing the below query to fetch data date wise. But in the result the
score is coming as null. How to get the score here.

curl -XPOST "10.203.251.142:9200/aricloud/_search" -d
'{
"query": {
"filtered": {
"query" : {
"match" : {
"CLOUD_TYPE" : "AWS-EC2"
}
},
"filter": {
"range": {
"NODE_CREATE_TIME": {
"to": "2014-03-14 18:43:55",
"from": "2014-03-14 16:22:32"
}
}
}
}
},
"sort" : {"NODE_ID" : "desc"},
"from" : 0,
"size" : 3
}'
==>
{
"took": 1,
"timed_out": false,
"_shards": {
"total": 3,
"successful": 3,
"failed": 0
},
"hits": {
"total": 5,
"max_score": null,
"hits": [
{
"_index": "aricloud",
"_type": "nodes",
"_id": "4",
"_score": null,
"_source": {
"NODE_ID": "12334",
"CLOUD_TYPE": "AWS-EC2",
"NODE_GROUP_NAME": "DATABASE",
"NODE_CPU": "5GHZ",
"NODE_HOSTNAME": "virtualnode.aricent.com",
"NODE_NAME": "aws-node4",
"NODE_PRIVATE_IP_ADDRESS": "10.123.124.126",
"NODE_PUBLIC_IP_ADDRESS": "125.31.108.72",
"NODE_INSTANCE_ID": "asw126",
"NODE_STATUS": "STOPPED",
"NODE_CATEGORY_ID": "14",
"NODE_CREATE_TIME": "2014-03-14 16:35:35"
},
"sort": [
"12334"
]
}
]
}
}

My first question is: why do you want the score? The score is used only for
sorting, and you're sorting on NODE_ID.

If you really want it (and there is a cost to computing the score) then you
can set track_scores to true.
