I need to get documents order by custom score, so i use script\_score:
```
$params = [
'index' => "questions",
'type' => "baichebao",
'body' => [
'from' => $from,
'size' => $size,
'sort' => [
"_score" => 'asc',
],
'query' => [
'bool' => [
'should' => [
'function_score' => [
'query' => [
'match' => [
'content' => '斯巴鲁',
]
],
'script_score' => [
"lang" => "groovy",
'params' => [
'now' => 1442184014,
],
'script' => 'now - doc["created_at"].value',
],
]
]
]
]
]
];
```
and I got the documents like
```
{
"code": 0,
"message": "处理成功",
"timestamp": 1442184477,
"im": true,
"result": {
"took": 6,
"timed_out": false,
"_shards": {
"total": 5,
"successful": 5,
"failed": 0
},
"hits": {
"total": 2680,
"max_score": null,
"hits": [
{
"_index": "questions",
"_type": "baichebao",
"_id": "2536263",
"_score": 740085.6,
"_source": {
"id": 2536263,
"content": "06年斯巴鲁力狮4at，近日出现行驶中熄火，油温过高指示灯闪一下就熄火，感觉车身下面确实有一点热，而且熄火前发动机转数还会乱跳，开着有点供不上油的感觉，时好时坏",
"uid": 877461,
"all_answer_count": 33,
"answer_users": 1,
"best_answer": 2951111,
"status": 1,
"is_closed": false,
"tags": [
"故障维修"
],
"channel_type": 3,
"channel_sub_type": 0,
"created_at": 1441386486,
"distrust": 0,
"is_expert": false,
"series_id": 0
},
"sort": [
740085.6
]
}
]
}
}
}
```
please notice the \_score is 740085.6, but my script will be : 1442184014-1441386486, how the elasticsearch got the strange score?
