elasticsearch高级功能系列之search template

四种search template方式： 

GET book/book/_search/template
{
  "file": "match_query",
  "params": {
    "field": "bookName.keyword",
    "value": "金明馆丛稿二编"
  }
}


GET book/book/_search/template
{
  "file":"match_tojson",
  "params": {
    "matchCondition":{
      "bookName.keyword":"金明馆丛稿二编"
    }
  }
}


GET book/book/_search/template
{
  "file":"match_join",
  "params": {
    "field":"bookName",
    "fields":["陈寅恪的最后20年","陈垣史源学杂文"]
  }
}


GET book/book/_search/template
{
  "file":"match_condition",
  "params": {
    "match_field":"bookAuthor",
    "match_value":"陈寅恪",
    "isCondition":true,
    "range_field":"bookPrice",
    "start":10,
    "end": 10
  }
}

以下4个模板文件放置在es安装目录config/scripts文件夹下，重启生效。

      }
  }
}


2、match_tojson.mustache文件：

{
    "query":{
      "match": {{#toJson}}matchCondition{{/toJson}}
      }
  }
}
