elasticsearch：做应该到过滤

Question

我希望做的是排除结果是不符合条件或anothor条件过滤搜索：

我想一个应该做的到的过滤器，但它失败：

POST /my_index/_search 
{ 
    "query": { 
    "bool": { 
     "filter": [ 
     { 
      "should": [ 
      { 
       "match": { 
       "type1_title": "searched match" 
       } 
      }, 
      { 
       "match": { 
       "type2_title": "searched match" 
       } 
      } 
      ] 
     } 
     ] 
    } 
    } 
} 

它引发的错误：

"error": { 
    "root_cause": [ 
     { 
     "type": "parsing_exception", 
     "reason": "[should] query malformed, no start_object after query name", 
     "line": 9, 
     "col": 21 
     } 
    ], 
    "type": "parsing_exception", 
    "reason": "[should] query malformed, no start_object after query name", 
    "line": 9, 
    "col": 21 
    }, 
    "status": 400 
} 

你知道，如果我们可以做一个或一个过滤器？

为什么不干脆bool/should，没有必要为filter这里

POST /my_index/_search 
{ 
    "query": { 
    "bool": { 
      "minimum_should_match": 1, 
      "should": [ 
      { 
       "match": { 
       "type1_title": "searched match" 
       } 
      }, 
      { 
       "match": { 
       "type2_title": "searched match" 
       } 
      } 
      ] 
    } 
    } 
} 

如果你真的想保持bool/filter/should结构，那么你需要做的是这样的：

POST /my_index/_search 
{ 
    "query": { 
    "bool": { 
     "filter": [ 
     { 
     "bool": { 
      "should": [ 
      { 
       "match": { 
       "type1_title": "searched match" 
       } 
      }, 
      { 
       "match": { 
       "type2_title": "searched match" 
       } 
      } 
      ] 
     } 
     } 
     ] 
    } 
    } 
}
