Elasticsearch数据对象

• _search
  • query
    • match
      • 理解如何分词的, 会对field分词再查询
      • field1:
        • query: “a b”
        • operator: “and”
        • minimum_should_match: “75%”
          • 匹配的query分词的最低占比
    • match_all
      • 默认，会查出所有文档
    • multi_match
      • query: “a b”
      • fields: [“field1”, “field2”]
    • match_phrase
      • 所有term命中，并且位置邻接
      • field1: “a b”
    • term
      • 确切查询
