elasticsearch java搜索查询

Question

我正在进行一个ecomerce网站，对于我的初始页面，我将把十大产品完成。 所以我正在做的是一个匹配all的搜索查询，由finish_dat>过滤而不是+ 1h并将大小限制为10（我不知道这是否是最好的方法...）

这里的事情是我想用这个查询创建一个配置（为了将来改变，让我们说，改为top20，或者现在过滤+ 1d），所以我将查询字符串读取到xml文件然后使用esClient.prepareSearch("products").setTypes("product").setSearchType(SearchType.QUERY_AND_FETCH).setQuery(myQuery).execute().actionGet();

问题是我正在尝试使用curl中的body查询：

{  "sort" : [
        { "finish_date" : {"order" : "asc"}}     
    ],
     "query" : {"match_all" : {}},
      "filter": {
        "range": {
          "finish_date": {
            "from": "now+1h"
          }
        }
      }

而且是错误的

有人知道怎么做吗？ （一个例子或指向正确的方向）??

您需要使用模板查询，这是官方支持的执行所需操作的方式，它还支持将模板存储在文件系统上，但是作为小胡子模板而不是XML。

您可以在http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/query-dsl-template-query.html上阅读有关模板查询的更多信息。

您实际上不需要在项目中安装小胡子，但是如果您感兴趣，可以在http://mustache.github.io/上阅读更多相关信息。 他们甚至有Java版本， https：//github.com/spullara/mustache.java 。
