Question

我正尝试使用matchQuery和fuzzyQuery从弹性搜索中获取文档，但是两个API的响应计数都相同。

例如：

方案1（带有matchQuery）

Am使用matchQuery搜索阀门，并使用下面的36 API获取matchQuery的计数

QueryBuilder qb = QueryBuilders.boolQuery()
                        .must(QueryBuilders.matchQuery("catalog_value", "valve"))
                       .filter(QueryBuilders.termQuery("locale", "en_US" ));

如果我搜索valves，也只会得到14个计数。

方案2（带有FuzzyQuery）

Am使用FuzzyQuery搜索阀门，并使用下面的34 API获取fuzzyQuery的计数

QueryBuilder qb = QueryBuilders.boolQuery()
                      .must(QueryBuilders.fuzzyQuery("catalog_value", "valve"))
                      .filter(QueryBuilders.termQuery("locale", "en_US"));

如果我搜索valves，也只会得到14个计数。实际上，如果我们使用FuzzyQuery，期望valve和valves的计数应该相同。

任何人都对FuzzyQuery API有所了解。

我使用的是ElasticSearch 6.2.3版本。

匹配valves的示例文档。

    {  
    "_index":"catalog",
    "_type":"doc",
    "_id":"517yxmQB1-MO2Tblt7C3",
    "_score":1.0,
    "_source":{  
       "catalog_name":"family451",
       "catalog_value":"These control valves range with actuation choices featuring.",
       "catalog_id":41065,
       "@version":"1",
       "locale":"en_US",
       "@timestamp":"2018-07-23T11:42:29.751Z"
}

请找到我的地图详细信息：

        PUT catalog
    {
      "settings": {
        "analysis": {
        "analyzer": {
           "value_analyzer": {
           "type": "custom",
            "tokenizer": "whitespace",
           "char_filter": [
            "html_strip"
           ],
           "filter": ["lowercase", "asciifolding"]
         }
       }
     }
    },
    "mappings": {
      "doc": {
        "properties": {
          "catalog_value": {
            "type": "text",
            "analyzer": "value_analyzer"
          },
          "catalog_id": {
            "type": "long"
          },
         "catalog_name":{
         "type":"keyword"
         },
         "locale":{
         "type":"keyword"
         }

        }
       }
      }
}

更新

我已经在以下情况下进行了测试，并且得到了以下计数。

valve    --> 17
valves   --> 7
valvess  --> 7
valvesss --> 8

val      --> 17
valv     --> 17

更新2

使用以下经过修改的查询并获得以下结果计数。

QueryBuilder qb1 = QueryBuilders.boolQuery()
            .must(QueryBuilders.fuzzyQuery("catalog_attr_value", "valve").boost(1.0f).prefixLength(0).fuzziness(Fuzziness.ONE).transpositions(true))
            .filter(QueryBuilders.termQuery("locale", "en_US"));


valve    --> 17
valves   --> 7
valvess  --> 8
valvesss --> 0

val      --> 17
valv     --> 17

更新3

使用下面的FuzzyQuery不能得到valve和Valves的正确结果计数。

QueryBuilder qb1 = QueryBuilders.boolQuery()
                    .must(QueryBuilders.fuzzyQuery("product_attr_value", keyword).boost(1.0f).prefixLength(0).fuzziness(Fuzziness.AUTO).transpositions(true));

对于valve和valves搜索，我总共得到10个结果计数（将计数限制为10），并且没有文档匹配在一起。

例如，以下是我在valve和valves搜索中获得的ID

ElasticSearch-FuzzyQuery Java API响应与matchQuery几乎相同
