如何在Java中使用JSON进行Elasticsearch查询? [英] How to make an Elasticsearch query with a JSON in Java?

问题描述

我正在尝试使用 Java 和 Elasticsearch 进行Elasticsearch搜索.弹性搜索为Java提供了API，这很酷.

I am trying to make an Elasticsearch search with Java and Elasticsearch. Elastic search provides API for Java and this is cool.

问题是，我希望在Java中创建一个方法，该方法接收一个字符串(应该是一个包含用于搜索的信息的JSON)，该字符串反映此对Elasticsearch的HTTP调用

The thing is, I wish to create a method in Java who receives a string (properly, a JSON containing information for searching) who reflects this HTTP call to Elasticsearch

curl -X GET 'http://localhost:9200/geocon/_search?q=first:"Sonya"'

但是我希望这种方法尽可能通用.

But I want this method as much general as possible.

所以问题是:是否可以使用Java API解析并转换1:1 HTTP请求到Elasticsearch?也许只将JSON字符串作为参数提供给Elasticsearch对象?

So the question is: is it possible to parse and translate 1:1 HTTP request to Elasticsearch with Java API? Maybe giving to the Elasticsearch object just the JSON string as parameter?

推荐答案

基本上，您需要执行以下操作:

Basically you need to do something like this:

String query = whatever_query...
SearchResponse response = esClient.prepareSearch(Configuration.PRIMARY_INDEX_NAME)
                    .setQuery(query)
                    .execute()
                    .actionGet();
