我正在使用angularjs作为前端和环回用于后端和弹性搜索数据库。
我有一个属性为的模型：
"name": {
"type": "string",
"required": true
},
"mobileNumber": {
"type": "string",
"required": true
},
"email": {
"type": "string"
},
"message": {
"type": "string",
"required": true
},
"quantity": {
"type": "number",
"required": true
},
"price": {
"type": "number",
"required": true
},
"status": {
"type": "string",
"required": true,
"default": "open"
}
},
数据为：
{
"_index": "XXXXXX",
"_type": "XXXXX",
"_id": "XXXXXXX",
"_version": 1,
"_score": 1,
"_source": {
"name": "aadil kirana",
"email": "[email protected]",
"message": "dfgfb dgfggf",
"quantity": 3434,
"price": 5454,
"status": "open",
"createdAt": "2017-12-19T14:53:41.727Z",
"updatedAt": "2017-12-19T14:53:41.727Z"
}
}
状态可以是打开，处理，关闭，拒绝和失败。
我想要的是按顺序获取数据，我可以通过created_At日期查看所有打开状态数据，然后按createdAt dat排序所有处理状态数据，等等....
我尝试使用环回过滤器：
filter = {
order: ['status ASC','createdAt DESC'],
};
但这首先给出了按日期排序的所有关闭状态数据，然后是按日期排序的所有打开状态数据，依此类推，该状态按字母顺序排序。
请帮助我获得理想的结果。
您可以将新属性作为statusOrder和define添加到数据中
在订购状态时按statusOrder而不是状态排序。
我想要的是按顺序获取数据，我可以通过created_At日期查看所有打开状态数据，然后按createdAt dat排序所有处理状态数据，等等....
解决方法可能是让Elasticsearch使用自定义顺序进行排序，例如在这种情况下，状态可以按开放顺序，然后是处理，然后是关闭，然后是拒绝，然后是失败。它可以用Function Score Query完成。还可以找到更多的见解here
批量插入的示例输入数据：
POST custom/sort/_bulk?pretty
{"index" : {"_index" : "custom"}}
{"status": "open", "createdAt": "2017-12-19T14:53:41.727Z"}
{"index" : {"_index" : "custom"}}
{"status": "open", "createdAt": "2017-12-18T14:53:41.727Z"}
{"index" : {"_index" : "custom"}}
{"status": "processing", "createdAt": "2017-12-19T14:53:41.727Z"}
{"index" : {"_index" : "custom"}}
{"status": "processing", "createdAt": "2017-12-17T14:53:41.727Z"}
{"index" : {"_index" : "custom"}}
{"status": "close", "createdAt": "2017-12-19T14:53:41.727Z"}
{"index" : {"_index" : "custom"}}
{"status": "close", "createdAt": "2017-12-19T15:53:41.727Z"}
{"index" : {"_index" : "custom"}}
{"status": "failure", "createdAt": "2017-12-19T10:53:41.727Z"}
{"index" : {"_index" : "custom"}}
{"status": "failure", "createdAt": "2017-12-19T14:59:41.727Z"}
{"index" : {"_index" : "custom"}}
{"status": "reject", "createdAt": "2017-12-19T14:53:40.727Z"}
{"index" : {"_index" : "custom"}}
{"status": "reject", "createdAt": "2017-12-19T14:53:41.727Z"}
弹性搜索的示例响应（没有自定义顺序）：
查询：
GET custom / sort / _search？filter_path = took，hits.total，hits.hits._score，hits.hits._source
{
"took": 0,
"hits": {
"total": 10,
"hits": [
{
"_score": 1,
"_source": {
"status": "processing",
"createdAt": "2017-12-19T14:53:41.727Z"
}
},
{
"_score": 1,
"_source": {
"status": "close",
"createdAt": "2017-12-19T14:53:41.727Z"
}
},
{

查询以模仿自定义排序：
GET custom/sort/_search?filter_path=took,hits.hits._id,hits.hits._score,hits.hits._source,hits.hits.sort
{
"query": {
"function_score": {
"boost_mode": "replace",
"query": {
"constant_score": {
"filter": {
"terms": {
"status.keyword": [
"open",
"processing",
"close",
"reject",
"failure"
]
}
}
}
},
"functions": [
{
"filter": {
"term": {
"status.keyword": "open"
}
},
"weight": 4
},
{
"filter": {
"term": {
"status.keyword": "processing"
}
},
"weight": 3
},
{
"filter": {
"term": {
"status.keyword": "close"
}
},
"weight": 2
},
{
"filter": {
"term": {
"status.keyword": "reject"
}
},
"weight": 1
},
{
"filter": {
"term": {
"status.keyword": "failure"
}
},
"weight": 0
}
]
}
},
"sort": [
{
"_score": {
"order": "desc"
},
"createdAt": {
"order": "asc"
}
}
]
}
