6搜索接口--3请求体

使用url进行检索会有一定限制，即当条件多的或者复杂的话就不太适合。这种情况下可以把检索要求写在请求体内。（又由于部分开源对于get请求不支持请求体，可以使用post方式）

{
    "from": 0,
    "size": 10,
    "query": {
        "bool": {
            "must": [
                {
                    "bool": {
                        "should": [
                            {
                                "term": {
                                    "status": 2
                                }
                            },
                            {
                                "term": {
                                    "tier": 3

                        ]
                    }
                },
                {
                    "term": {
                        "media_id": 102050
                    }
                }
            ],
            "should": [
                {
                    "term": {
                        "actions": 3
                    }

    ]
}

以上是总结

从0条开始，查看10条

GET /_search
{
    "from" : 0, "size" : 10,
    "query" : {
        "term" : { "user" : "kimchy" }
    }
}
排序，根据post_date进行升序
GET /my_index/my_type/_search

{

    "sort" : [

        { "post_date" : {"order" : "asc"}}

    ],

    "query" : {

        "term" : { "user" : "kimchy" }

    }

}

asc：升序
desc：降序
除此外，还可以根据复杂类型进行排序，不过需要对复杂类型定义需要排序的定义

字段过滤（即那些字段不展示，那些字段展示）

GET /_search
{
    "_source": "obj.*",
    "query" : {
        "term" : { "user" : "kimchy" }
    }
}

或者

GET /_search
{
    "_source": [ "obj1.*", "obj2.*" ],
    "query" : {
        "term" : { "user" : "kimchy" }
    }
}

或者

GET /_search
{
    "_source": {
        "includes": [ "obj1.*", "obj2.*" ],
        "excludes": [ "*.description" ]
    },
    "query" : {
        "term" : { "user" : "kimchy" }
    }
}

搜索颜色为红色且品牌为gucci的数据

GET /shirts/_search
{
  "query": {
    "bool": {
      "filter": [
        { "term": { "color": "red"   }},
        { "term": { "brand": "gucci" }}
      ]
    }
  }
}

对上面的数据分组展示

GET /shirts/_search
{
  "query": {
    "bool": {
      "filter": [
        { "term": { "color": "red"   }},
        { "term": { "brand": "gucci" }}
      ]
    }
  },
  "aggs": {
    "models": {
      "terms": { "field": "model" } 
    }
  }
}

高亮content列

GET /_search
{
    "query" : {
        "match": { "content": "kimchy" }
    },
    "highlight" : {
        "fields" : {
            "content" : {}
        }
    }
}

解释分数如何计算

GET /_search
{
    "explain": true,
    "query" : {
        "term" : { "user" : "kimchy" }
    }
}

当前文档的版本

GET /_search
{
    "version": true,
    "query" : {
        "term" : { "user" : "kimchy" }
    }
}

排除分数小于指定值

GET /_search
{
    "min_score": 0.5,
    "query" : {
        "term" : { "user" : "kimchy" }
    }
}
