Elasticsearch过滤结果按ID排除 [英] Elasticsearch filter results excluding by id

问题描述

我需要返回不包含具有特定ID的文档的结果. Elasticsearch允许我们指定允许使用哪些ID，但是我看不到任何禁止某些ID的方法.就我而言，我不想返回用户已经看到的内容，因此每个用户的列表都会有所不同.

I need to return results that do not include docs with certain ids. Elasticsearch allows us to specify which ids are allowed but I see no way to disallow certain ids. In my case I want to not return things the user has already seen so the list will be different for each user.

推荐答案

您可以通过添加一个bool/must_not过滤器来实现此目的，该过滤器包含一个ids过滤器，该过滤器具有您不想显示的ID数组，如下所示:

You can achieve this by adding a bool/must_not filter containing an ids filter with an array of ids you don't want to appear, like this:

{
  "query": {
    "bool": {
      "must": [
         ...                    <--- your other filters go here
      ],
      "must_not": [
        {
          "ids": {
            "values": [
              "id1", "id2"      <--- add all the ids you DON'T want in here
            ]
          }
        }
      ]
    }
  }
}
