multi_match中query词的问题

GET test_index/_search
{
  "query": {
    "bool": {
      "should": [
        {"match_phrase": {
          "title": "red hat"
        }},
        {"match": {
          "title": "cat"
        }}
      ]
    }
  }
}

(⊙o⊙)…    "multi_match" 用来进行多字段匹配的，如果你要对于同一个字段的内容进行匹配，可以选择match进行操作。

DELETE index_test



POST index_test/_bulk

{"index":{"_id":1}}

{"cont":"red hat is excellent software."}

{"index":{"_id":2}}

{"cont":"red looks like hat."}

{"index":{"_id":3}}

{"cont":"red and hat are uesd in the cat."}

{"index":{"_id":4}}

{"cont":"The cat has the red hat."}

{"index":{"_id":5}}

{"cont":"The red hat belongs to the cat."}

{"index":{"_id":6}}

{"cont":"The cat wears a hat."}



#red hat 和 cat 可以不在同一个内容中

GET index_test/_search

{

  "query": {

    "bool": {

      "must": [

        {

          "match_phrase": {

            "cont": "red hat"

          }

        }

      ],

      "should": [

        {

          "match": {

            "cont": "cat"

          }

        }

      ]

    }

  }

}



#red hat 和 cat 一定要在同一内容中

GET index_test/_search

{

  "query": {

    "bool": {

      "must": [

        {

          "match_phrase": {

            "cont": "red hat"

          }

        },

        {

          "match": {

            "cont": "cat"

          }

        }

      ]     

    }

  }

}

希望以上内容对你有所帮助。
