elasticsearch-high-level-restclient

问题 There are two Java Rest clients named Java High Level REST Client and Java Low Level REST Client to integrate with Elastic Search. When did Java High Level REST Client got introduced in Elastic search and why? 回答1: If you follow the official documentation you will get to know the differences, how they work and the reason behind adding the Java High Level REST Client(JHLRC) . Coming to the first question when JHLRC was added, as shown in official doc, it was added in 6.0.0-beta1 release.

问题 I have been stuck with this issue for a while now and any assistance is appreciated. I am running Spring Boot version 2.2.0 with the ElasticSearch high-level REST Client version 6.4.3 and using version 3.2.0 for the Spring-Data-Elasticsearch version. I am getting the error below. I have tried the following attempts to fix but none do. Change Spring Boot Version multiple times Change ES version multiple times I have cleared my .m2 folder and redownloaded the maven dependencies multiple times.

问题 I'm new to Elastic search. Integrated my Spring boot application with Elastic search through Java High Level Rest Client . I've configured JHLRC bean as below and it worked fine: @Bean(destroyMethod = "close") public RestHighLevelClient client() { RestHighLevelClient client = new RestHighLevelClient( RestClient.builder(new HttpHost("localhost", 9200, "http"))); return client; } Started exploring the security for Elasticsearch, after setup certificate and passwords, I've enabled security by

问题 My end goal is to build a faceted search page using an Elasticsearch index. I am following this tutorial Why is this aggregation query not working with my data? I think I need to change my aggregation clause, so that it refers to the keywords rather than the field, but do not know the syntax. Here is my data. I mean the response to the following Postman command: GET https://<elastic username>:<elastic password>@<elastic url>:<port number>/<my index name>/_search Here's the response: { "took":

问题 We are dealing in querying large amount of data from our elastic search server. However, in random scenarios the connection created by the High Level Rest client is not getting released and it's blocking our code flow. Rest client opens connection to get the data but doesn't return. Although we have specified the timeouts as well as shown below, but the rest client doesn't timeout as well. RestHighLevelClient client = new RestHighLevelClient(RestClient.builder(httpHost)

问题 We are trying to use a request timeout in our queries but it doesn't seem to be working for us. Here're the things we have done as part of setup: search.default_allow_partial_results : false (on server side as well as client side) Set the timeout of 10ms in every search query that we hit. (client side) Apart from these, we have global timeouts set as shown in the code below: RestHighLevelClient client = new RestHighLevelClient(RestClient.builder(httpHost).setRequestConfigCallback(
