【中文标题】具有聚合的同义词分析器给出“无法解析名称为 [匹配] 的 BaseAggregationBuilder：找不到解析器”错误

【英文标题】：Synonym analyzer with aggregation gives "unable to parse BaseAggregationBuilder with name [match]: parser not found" error

【问题描述】：

在我将同义词分析器添加到映射之前，我有一个 Elastic Search 项目，我的聚合和过滤器工作正常。 当前工作映射：

"settings": 
        "analysis": 
            "normalizer": 
                "lowercase": 
                "type": "custom",
                "filter": ["lowercase"]
                
            
        
    ,
 "mappings": 
        "doc": 
            "dynamic": "false",
            "properties": 
              "primarytrades": 
                    "type": "nested",
                    "properties" :
                        "name": 
                            "type": "text",
                            "fields": 
                                "keyword": 
                                    "type": "keyword",
                                    "ignore_above": 256,
                                    "normalizer": "lowercase"

为了添加同义词搜索功能，我使用同义词分析器更改了映射，如下所示：

 "settings": 
      "analysis": 
        "normalizer": 
          "lowercase": 
            "type": "custom",
            "filter": [ "lowercase" ]
          
        ,
        "analyzer": 
          "synonym_analyzer": 
            "type": "custom",
            "tokenizer": "standard",
            "filter": [ "lowercase", "my_synonyms" ]
          
        ,
        "filter": 
          "my_synonyms": 
            "type": "synonym",
            "synonyms": [ "piping, sink, plumbing" ],
            "updateable": true
          
        
      
    ,
    "mappings": 
        "doc": 
            "dynamic": "false",
            "properties": 
                "primarytrades": 
                    "type": "nested",
                    "properties" :
                      "name": 
                        "type": "text",
                        "fields": 
                          "keyword": 
                            "type": "keyword",
                            "ignore_above": 256
                          ,
                          "analyzed": 
                            "type": "text",
                            "analyzer": "standard",
                            "search_analyzer": "synonym_analyzer"
                          
                        
                      
                    
              
        
    

此外，我将查询更改为使用 search_analyzer，如下所示：

"aggs":"filter_trades":"aggs":"nested_trades":"aggs":"autocomplete_trades":"match":"field":"primarytrades.name.analyzed" ,"include":".*p.*l.*u.*m.b.","size":10,"nested":"path":"primarytrades ","filter":"nested":"path":"primarytrades","query":"bool":"should":["match":"primarytrades.name": "fuzziness":2,"query":"plumb","search_analyzer":"synonym_analyzer","match_phrase_prefix":"primarytrades.name":"query":"plumb","search_analyzer" :"synonym_analyzer"],"query":"bool":"filter":["nested":"path":"primarytrades","query":" bool":"should":["match":"primarytrades.name":"fuzziness":2,"query":"plumb","search_analyzer":"synonym_analyzer","match_phrase_prefix ":"primarytrades.name":"query":"plumb","search_analyzer":"synonym_analyzer"]]

我收到此错误： "type": "named_object_not_found_exception", “原因”：“[8:24] 无法解析名称为 [匹配] 的 BaseAggregationBuilder：找不到解析器”

有人可以帮我更正查询吗？

提前致谢！

【问题讨论】：

对于聚合我在 "significant_text" 上尝试了 "field": "primarytrades.name.analyzed" 并且错误消失了，但我的存储桶没有任何值。同样，我在“terms”上使用了“field”：“primarytrades.name.keyword”，但我没有得到任何桶的值。如何根据同义词分析器和过滤器获取存储桶值？

【参考方案1】：

在您的match 查询中，您需要指定analyzer 而不是search_analyzer。 search_analyzer 只是映射部分的有效关键字。

              
                "match": 
                  "primarytrades.name": 
                    "fuzziness": 2,
                    "query": "plumb",
                    "analyzer": "synonym_analyzer"      <--- change this
                  
                
              ,
