Question

我试图实现模板查询的功能。请参阅http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/search-template.html

的最后一节

我使用sense添加了一个查询模板。现在需要通过elasticsearch的JAVA API，我需要执行此查询模板并将结果存储在SearchResponse中。但是，我无法找到任何与查询模板相关的API。唯一可用的类文件是TemplateQueryBuilder。这个类完美地构造了模板查询，但我不确定从Client调用哪个方法来传递TemplateQueryBuilder的对象。感谢您的帮助。

Answer 1

以下是如何操作：

SearchRequestBuilder request = client;.prepareSearch();
request.setTemplateName(templateName);
request.setTemplateType(ScriptService.ScriptType.INDEXED);
request.setTemplateParams(templateParams);
SearchResponse response = request.get();

你只需解析响应对象然后..

Answer 2

Note that with API version 2.X, as request.setTemplateX methods are deprecated, you should use a different approach. Either you can use request.setTemplate(Template template) which is similar to the accepted answer, or you can go with the more generic QueryBuilders approach:

QueryBuilder qb = QueryBuilders.templateQuery(
    "templateName",
    ScriptService.ScriptType.FILE,
    templateParams);
