在弹性搜索中查找术语的出现

Question

我在JAVA 中对 autosuggest使用弹性搜索，需要在索引中存储术语及其出现。虽然索引产品，可以多次索引特定字符串。为了避免这种情况，如果它已经存储，我们必须更新出现索引项。弹性搜索POJO：

@Document(indexName = "autosuggest", type = "autosuggest")

public class Autosuggest {

@Id

@Field(pattern ="id")

private String id;

@Field(pattern ="completion")

private Completion completion;

@Field(pattern ="occurence")

private Integer occurence;

public String getId() {

    return id;

}

public Completion getCompletion() {

    return completion;

}

public void setCompletion(Completion completion) {

    this.completion = completion;

}

public Integer getOccurence() {

    return occurence;

}

public void setOccurence(Integer occurence) {

    this.occurence = occurence;

}

}

完成对象

public class Completion {

private List<String> input;

private Integer weight;

public List<String> getInput() {

    return input;

}

public void setInput(List<String> input) {

    this.input = input;

}

public Integer getWeight() {

    return weight;

}

public void setWeight(Integer weight) {

    this.weight = weight;

}

public Completion(List<String> input, Integer weight) {

    super();

    this.input = input;

    this.weight = weight;

}

}

弹性搜索中的示例对象

  {

    "_index" : "autosuggest",

    "_type" : "autosuggest",

    "_id" : "BUj0zGUBr5AQqSH41l0m",

    "_score" : 1.0,

    "_source" : {

      "completion" : {

        "input" : [

          "Casual Shirts for Men"

        ],

        "weight" : 2

      },

      "occurence" : 1

    }

  }

如果该术语已在弹性搜索中编入索引，我该如何更新出现？

Answer 1

这有效：&nbsp; "query": {&nbsp; &nbsp; &nbsp;"match": {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp;"completion": "Casual Shirts for Men"&nbsp; &nbsp; &nbsp; }&nbsp; }

Answer 2

将此作为答案发布，因为我无法发表评论。@Priancy：您使用的查询似乎不正确。请在下面找到正确的查询。我已使用您在问题中提供的示例对象测试了此查询。"query": {&nbsp; &nbsp; "match": {&nbsp; &nbsp; &nbsp; "completion.input": "Casual Shirts for Men"&nbsp; &nbsp; }}还请通过此链接了解如何跳过此方法并增加发生次数。谢谢
