We have started elasticsearch in the previous article, and then we can communicate with elasticsearch, such as inserting data, retrieving data, deleting data, and so on. Elasticsearch provides two ways to communicate with Java APIs and restful APIs. Java

Use of Java APIs in Elasticsearch 6.01: Create Elasticsearch client using Java API PackageCom.search.elasticsearch;Importorg.elasticsearch.client.transport.TransportClient;Importorg.elasticsearch.common.settings.Settings;Importorg.elasticsearch.common.transport.TransportAddr

ClientThere are several places to use Java client : Perform standard index, GET, delete, and search in a cluster that exists Perform administrative tasks in the cluster Start all nodes when you want to run Elasticsearch nested within your application or when you want to run unit tests or set tests Getting a client is very easy, and the most common steps are as follows: Create

Elasticsearch provides developers with a set of restful interfaces based on the HTTP protocol, and only needs to construct a rest request and parse the JSON returned by the request for access to the Elasticsearch server. Elasticsearch API interface is rich in functionality, including clustering, monitoring, deployment

Java APIThis section describes the Java APIs supported by Elasticsearch. All elasticsearch operations are performed using the client object. Essentially, all operations are performed in parallel.In addition, operations in the client are likely to accumulate and execute through bulk.MavenElasticsearch is hosted in the M

":" String "}," raw ": {" type ":" string "," index ":" Not_analyzed "}}}}The above file says that we define its mapping for Index_type, the index type. The point is to map the name field to two, one to name the index analysis, and the other to not analyze raw, which will not split the phrase New York. So when we do the search, we can do the term aggregation for the Name.raw field and get the number of occurrences in all cities. Term Aggregation's The rest method requests are written as follows

Search APIThe search API allows developers to execute a search query that returns search information that satisfies the query criteria. It can be executed across indexes and across types. Queries can be either Java query API or Java filtering API. The request body of the que

By adding search data through the rest API, reading the official documentation reveals that Elasticsearch supports dynamic mapping, but there are a lot of questions and listen slowly. This article mainly tells about three points content: 1 Elasticsearch Common REST API 2

The deletion of Elasticsearch is also very flexible, next time I introduce, DeleteByQuery the way. Today, we will introduce a deletion based on the ID.

Elasticsearch provides a very comprehensive and powerful rest API that you can use to interact with your cluster. The few things you can do with the API are as follows: Check your cluster, node, and index health status and statistics Managing cluster, node, and index data and metadata Perform crud (Create, read, update, and delete) indexes and se

The condition is then FacetBuilders reached in the query request.SearchResponse sr = node.client().prepareSearch() /* your query */ ) .addFacet( /* add a facet */ ) .execute().actionGet();To build the facets request, you need to use the FacetBuil

可以使用行命令 curl 通过9200端口与 Elasticsearch 的 RESTful API 进行通信。Elasticsearch RESTful API规范例如，计算集群中文件的数量，我们就可以使用： curl -XGET ‘http://localhost:9200/_count?pretty‘-d ‘{ "query": { "match_all": {} }}详细说明：1.相应的 HTTP 请求方法 或者 变量 : GET, POST, PUT, HEAD 或者 DELETE。2.集群中任意一个节点的访问协议、主机名以及端口。3.请求的路径。4.任意一个查询后再加上 ?pretty 就可以生成 更加美观 的JSON
