我在JAVA 中對(duì) autosuggest使用彈性搜索，需要在索引中存儲(chǔ)術(shù)語及其出現(xiàn)。雖然索引產(chǎn)品，可以多次索引特定字符串。為了避免這種情況，如果它已經(jīng)存儲(chǔ)，我們必須更新出現(xiàn)索引項(xiàng)。彈性搜索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;}}完成對(duì)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;}}彈性搜索中的示例對(duì)象  {    "_index" : "autosuggest",    "_type" : "autosuggest",    "_id" : "BUj0zGUBr5AQqSH41l0m",    "_score" : 1.0,    "_source" : {      "completion" : {        "input" : [          "Casual Shirts for Men"        ],        "weight" : 2      },      "occurence" : 1    }  }如果該術(shù)語已在彈性搜索中編入索引，我該如何更新出現(xiàn)？
