提前键入搜索未在弹性搜索中获得预期结果

如何解决提前键入搜索未在弹性搜索中获得预期结果

我正在尝试在搜索框中构建提前输入搜索功能。我使用以下属性和设置创建了索引。

{"index.number_of_shards":3,"index.number_of_replicas":2,"analysis":{"filter":{"autocomplete_filter":{"type":"edge_ngram","min_gram":1,"max_gram":20}},"analyzer":{"autocomplete":{"type":"custom","tokenizer":"standard","filter":["autocomplete_filter","lowercase"]}}}}

然后我尝试使用 nodejs elasticsearch 客户端 api 获取结果。

module.exports.search = async function (req,res) {
  console.log(req.query.q);
  var queryStrings = req.query.q.split(" ");
  client.search({
    index: "skills",body: {
      "suggest": {
        "suggestions": {
            "text": queryStrings,"completion": {
                "field": "skill","fuzzy": {
                     "fuzziness": "auto"
                 }
             }
         }
     }
    },},(err,result) => {
    if(err) console.log(err)
    return res.status(200).send({
      statusCode: 200,content: {
        data: result,}
    });
  });
};

上述查询的输出是

[{
    "suggest": {
        "suggestions": [{
            "text": "jav","offset": 0,"length": 3,"options": [{
                    "text": "jaas","_index": "skills","_type": "_doc","_id": "15706","_score": 2,"_source": {
                        "skill": "jaas"
                    }
                },{
                    "text": "jabaco","_id": "21028","_source": {
                        "skill": "jabaco"
                    }
                },{
                    "text": "jabberd2","_id": "34684","_source": {
                        "skill": "jabberd2"
                    }
                },{
                    "text": "jabbr","_id": "35577","_source": {
                        "skill": "jabbr"
                    }
                },{
                    "text": "jacc","_id": "34873","_source": {
                        "skill": "jacc"
                    }
                }
            ]
        }]
    }
}]

上述代码的问题在于它正在获取不相关的结果。而当我使用 cURL 执行请求时，它会获取适当的结果。需要帮助。

curl --location --request POST 'http://localhost/skills/_search' \
--header 'Content-Type: application/json' \
--data-raw '{
  "query" : {
    "match": {
      "skill": "java"
    }
  },"suggest" : {
    "my-suggestion" : {
      "text" : "ava","term" : {
        "field" : "skill"
      }
    }
  }
}'

上述 cURL 命令的输出是

{
    "hits": [{
            "_index": "skills","_id": "17146","_score": 8.592034,"_source": {
                "skill": "java1.4"
            }
        },{
            "_index": "skills","_id": "43979","_source": {
                "skill": "java-9"
            }
        },"_id": "44652","_source": {
                "skill": "java-10"
            }
        },"_id": "1268","_score": 8.591877,"_source": {
                "skill": "java"
            }
        },"_id": "25608","_source": {
                "skill": "java-6"
            }
        },"_id": "28709","_source": {
                "skill": "java-8"
            }
        },"_id": "223","_score": 7.970926,"_id": "4929","_id": "6175","_source": {
                "skill": "java8"
            }
        },"_id": "6563","_source": {
                "skill": "java"
            }
        }
    ]
}

请让我知道我在这里遗漏了什么。感谢您的回复。
