Spring-Data-ElasticSearch-Registing自定义分析器

Question

{
    "settings": {
        "number_of_shards": 1,
        "analysis": {
            "filter": {
                "autocomplete_filter": {
                    "type": "edge_ngram",
                    "min_gram": 1,
                    "max_gram": 20
                }
            },
            "analyzer": {
                "autocomplete": {
                    "type": "custom",
                    "tokenizer": "standard",
                    "filter": [
                        "lowercase",
                        "autocomplete_filter"
                    ]
                }
            }
        }
    }
}

@Document(indexName = "estabelecimento")
@Setting(settingPath = "/elasticsearch/autocomplete-analyser.json")
public class ESEstabelecimento {

    private Long id;
    @Field(type = FieldType.String, indexAnalyzer = "autocomplete")
    private String nome;
    private String razaoSocial;
    private String tipoEstabelecimento;
    @Field(type = FieldType.Object)
    private ESCidade cidade;
}

我无法确定问题的原因，我不知道是分析器无效还是elasticsearch甚至找到了autocomplete-analyser.json文件。我该怎么解决这个？

我想您需要从json文件中删除字段“settings”:并只放入内容。

而不是使用：

{
"settings": {
    ....
   }
}

只需使用：

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