我正在尝试在 ElasticSearch 服务器上做一个简单的搜索并得到以下错误

ElasticsearchStatusException[Elasticsearch exception [type=illegal_argument_exception, reason=request [/recordlist1/_search] contains unrecognized parameter: [ccs_minimize_roundtrips]]]

查询字符串： {"query":{"match_all":{"boost":1.0}}}

我正在使用：elasticsearch-rest-high-level-client（maven artifact）

SearchRequest searchRequest = new SearchRequest(INDEX);
        
        SearchSourceBuilder searchSourceBuilder = new SearchSourceBuilder();
        searchSourceBuilder.query(QueryBuilders.matchAllQuery());
        searchRequest.source(searchSourceBuilder);
        
        try 
        {
            
            
            System.out.print(searchRequest.source());
            SearchResponse response = getConnection().search(searchRequest,RequestOptions.DEFAULT);
            SearchHit[]  results=response.getHits().getHits();
            for(SearchHit hit : results)
            {
                String sourceAsString = hit.getSourceAsString();
                System.out.println( gson.fromJson(sourceAsString, Record.class).year);
            }
            
        } 
        catch(ElasticsearchException e) 
        {
            e.getDetailedMessage();
            e.printStackTrace();
        } 
        catch (java.io.IOException ex)
        {
            ex.getLocalizedMessage();
            ex.printStackTrace();
        }

我在 Spring Boot 应用程序中使用 ElasticSearch 高级客户端 Java API。我想记录使用高级客户端 API 构建的查询以进行调试。

我的问题是我的 application.properties 文件中需要什么样的设置才能打开从我的应用程序构建的 JSON 查询？

我在 application.properties 文件中尝试了以下属性。但是，它不会打印使用各种查询构建器构建的 JSON 查询。

logging.level.org.elasticsearch.client=TRACE
logging.level.org.elasticsearch.client.sniffer=TRACE
logging.level.org.elasticsearch=TRACE

我想通过 JAVA API 对字段进行映射，但失败了。以下是详细信息：

我的数据结构是：

{
  "mje-test-execution-id": "464b66ea6c914ddda217659c84a3cb9d",
  "jvm-free-memory": 315245608,
  "jvm-total-memory": 361758720,
  "system-free-memory": 0,
  "jvm-max-memory": 7600078848,
  "system-total-memory": 34199306240,
  "memory-time-stamp": "2020-03-12T05:12:16.835Z",
  "mje-host-name": "CN-00015345",
  "mje-test-suite-name": "SCF Test no mje version",
  "mje-version": "1.8.7771-SNAPSHOT",
  "mje-test-artifact-id": "msran-regression-tests",
  "mje-test-version": "1.8.7771-SNAPSHOT",
  "stp-id": "vran-stp",
  "mje-test-location": {
    "lat": 58.41,
    "lon": 15.62
  }
}

我想做的是：将“mje-t​​est-location”类型设置为“geo_point”

我的代码片段：

public void postMapping(String indexName, String field, String type) throws IOException {
        GetIndexRequest request = new GetIndexRequest(indexName);

        boolean exists = client.indices().exists(request, RequestOptions.DEFAULT);
        if (!exists) {
            LOGGER.info("index {} does not exist. Now to post mapping.", indexName); …

我是开放搜索的新手。

我正在努力利用 OpenSearch 的 Java SDK。
我知道这包含两个供客户端使用的 java 类：

1. OpenSearchClient
2. RestHighLevelClient

我知道RestHighLevelClient在elasticsearch 7.x 中已弃用，并且驼峰式和蛇形式之间的转换是不可能的。

因此，在使用 时OpenSearchClient，我发现 的包装器查询不存在OpenSearchClient。

所以，我想问的是：
如何使用 进行包装查询OpenSearchClient？

当前的逻辑RestHighLevelClient是：

String query = "{\"term\":{\"name.keyword\":{\"value\":\"bob\"}}}"

BoolQueryBuilder queryBuilder = new BoolQueryBuilder()
        .must(new WrapperQueryBuilder(query));

RestClientBuilder builder = getRestClientBuilder();
SearchResponse searchResponse;
try (RestHighLevelClient highLevelClient = new RestHighLevelClient(builder)) {
    SearchSourceBuilder searchSourceBuilder = new SearchSourceBuilder()
            .query(queryBuilder).from(0).size(10);

    SearchRequest searchRequest = Requests.searchRequest("my_index")
            .source(searchSourceBuilder);   

    searchResponse = highLevelClient.search(searchRequest, RequestOptions.DEFAULT); 
}

感谢您分享您的知识。

我的 API 版本是 6.3，我尝试创建索引。失败说“映射定义不能嵌套在类型 [_doc] 下，除非 include_type_name 设置为 true”。这是我的代码：

CreateIndexRequest indexRequest = new CreateIndexRequest("user");

request.source("{\n" +
        "    \"settings\" : {\n" +
        "        \"number_of_shards\" : 1,\n" +
        "        \"number_of_replicas\" : 0\n" +
        "    },\n" +
        "    \"mappings\" : {\n" +
        "        \"_doc\" : {\n" +
        "            \"properties\" : {\n" +
        "                \"message\" : { \"type\" : \"text\" }\n" +
        "            }\n" +
        "        }\n" +
        "    },\n" +
        "    \"aliases\" : {\n" +
        "        \"twitter_alias\" : {}\n" +
        "    }\n" + …

我正在使用 Elasticsearch 7.3 并且无法将其连接到我的 Spring boot 应用程序以使用ElasticsearchRepository.

@Configuration
public class ElasticSearchConfig {
    @Value("${elasticsearch.host:localhost}")
    public String host;
    @Value("${elasticsearch.port:9300}")
    public int port;

    public String getHost() {
        return host;
    }

    public int getPort() {
        return port;
    }

    private int timeout = 60;

    @Bean
    public RestHighLevelClient client() {
        System.out.println("host:" + host + "port:" + port);
        final CredentialsProvider credentialsProvider = new BasicCredentialsProvider();
        credentialsProvider.setCredentials(AuthScope.ANY, new UsernamePasswordCredentials("elastic", "changeme"));
        RestClientBuilder builder = RestClient.builder(new HttpHost("localhost", 9200, "http")).setHttpClientConfigCallback(httpClientBuilder -> httpClientBuilder.setDefaultCredentialsProvider(credentialsProvider));
        builder.setRequestConfigCallback(requestConfigBuilder -> requestConfigBuilder.setConnectTimeout(timeout * 1000).setSocketTimeout(timeout * 1000)
                .setConnectionRequestTimeout(0)); …
