14、基于multi_match 使用cross-fields search

造数据

POST /forum/_bulk
{ "update": { "_id": "1"} }
{ "doc" : {"sub_title" : "learning more courses"} }
{ "update": { "_id": "2"} }
{ "doc" : {"sub_title" : "learned a lot of course"} }
{ "update": { "_id": "3"} }
{ "doc" : {"sub_title" : "we have a lot of fun"} }
{ "update": { "_id": "4"} }
{ "doc" : {"sub_title" : "both of them are good"} }
{ "update": { "_id": "5"} }
{ "doc" : {"sub_title" : "haha, hello world"} }

执行查询

GET /forum/_search
{
  "query": {
    "multi_match": {
      "query": "Peter Smith",
      "type": "cross_fields",
      "fields": [
        "author_first_name",
        "author_last_name"
      ]
    }
  }
}

等价于

GET /forum/_search
{
  "query": {
    "multi_match": {
      "query": "Peter Smith",
      "type": "best_fields",
      "fields": [
        "author_first_name",
        "author_last_name"
      ]
    }
  }
}

返回结果
