Question

我有以下基于注释的弹性搜索配置，我已设置索引不被分析，因为我不希望这些字段被标记化：

    @Document(indexName = "abc", type = "efg")
    public class ResourceElasticSearch {
    @Id
    private String id;
    @Field(type = FieldType.String, index = FieldIndex.not_analyzed)
    private String name;
    @Field(type = FieldType.String, store = true)
    private List<String> tags = new ArrayList<>();
    @Field(type = FieldType.String)
    private String clientId;
    @Field(type = FieldType.String, index = FieldIndex.not_analyzed)
    private String virtualPath;
    @Field(type = FieldType.Date)
    private Date lastModifiedTime;
    @Field(type = FieldType.Date)
    private Date lastQueryTime;
    @Field(type = FieldType.String)
    private String modificationId;
    @Field(type = FieldType.String)
    private String realPath;
    @Field(type = FieldType.String)
    private String extension;
    @Field(type = FieldType.String)
    private ResourceType type;

是否可以通过使用注释使名称，virtualPath和标签上的搜索不区分大小写？搜索看起来像这样，需要通过通配符搜索：

private QueryBuilder getQueryBuilderForSearch(SearchCriteria criteria) {
    String virtualPath = criteria.getPath();

    return boolQuery()
            .must(wildcardQuery("virtualPath", virtualPath))
            .must(wildcardQuery("name", criteria.getName()));
}

不太可能你想做什么，它不是关于Spring Data配置，而是关于Elasticsearch本身：你将数据索引为not_analyzed并且它将保持这种状态。

此外，如果您想要不区分大小写的数据，我建议使用keyword analyzer和lowercase token filter进行索引。

我根据Andrei Stefan的建议发现了一些与使用注释类似的结果：

    @Bean
    public Client client() throws IOException {
    TransportClient client = new TransportClient();
    TransportAddress address = new InetSocketTransportAddress(env.getProperty("elasticsearch.host"), Integer.parseInt(env.getProperty("elasticsearch.port")));
    client.addTransportAddress(address);

    XContentBuilder settingsBuilder = XContentFactory.jsonBuilder()
            .startObject()
            .startObject("analysis")
            .startObject("analyzer")
            .startObject("keyword")
            .field("tokenizer", "keyword")
            .array("filter", "lowercase")
            .endObject()
            .endObject()
            .endObject()
            .endObject();
    if (!client.admin().indices().prepareExists("abc").execute().actionGet().isExists()) {
        client.admin().indices().prepareCreate("abc").setSettings(settingsBuilder).get();
    }
       return client;
    }

您可以添加消耗文件路径的@Setting，在@Document之后，设置文件应该包含这样的json： {"analysis":{"analyzer":{"case_insensitive":{"type":"custom","tokenizer":"whitespace","char_filter":["html_strip"],"filter":["lowercase","asciifolding"]}}}} 和带有分析器 @Field(type = FieldType.Keyword, analyzer = "case_insensitive")

的字段注释
