第十三篇 elasticsearch的Query DSL搜索语法

Query DSL基本语法

{
    QUERY_NAME: {
        ARGUMENT: VALUE,
        ARGUMENT: VALUE,...
    }
}

{
    QUERY_NAME: {
        FIELD_NAME: {
            ARGUMENT: VALUE,
            ARGUMENT: VALUE,...
        }
    }
}

示例：

GET /test_index/test_type/_search 
{
  "query": {
    "match": {
      "test_field": "test"
    }
  }
}

多条件搜索
搜索需求：title必须包含elasticsearch，content可以包含elasticsearch也可以不包含，author_id必须不为111

GET /website/article/_search
{
  "query": {
    "bool": {
      "must": [
        {
          "match": {
            "title": "elasticsearch"
          }
        }
      ],
      "should": [
        {
          "match": {
            "content": "elasticsearch"
          }
        }
      ],
      "must_not": [
        {
          "match": {
            "author_id": 111
          }
        }
      ]
    }
  }
}

模拟一个更加复杂的语法

GET /test_index/_search
{
    "query": {
            "bool": {
                "must": { "match":   { "name": "tom" }},
                "should": [
                    { "match":       { "hired": true }},
                    { "bool": {
                        "must":      { "match": { "personality": "good" }},
                        "must_not":  { "match": { "rude": true }}
                    }}
                ],
                "minimum_should_match": 1
            }
    }
}
