解决方案

首先，您需要确保在建立索引时将用户ID添加到字段中索引中的文档中，我们将其称为user_id.

在紧要关头，您可以将字段添加到用户在幕后输入的查询字符串中，然后再将其发送到查询解析器.因此，无论输入什么查询，都在其末尾添加"AND user_id:4"(其中4是包含当前用户ID的变量的值).

解决方案

First, you need to ensure that the user id is being added to the document in the index in a field when you index, let's call it user_id.

In a pinch, you can add a field to the query string entered by the user behind the scenes before you send it to the query parser. So, take whatever query was entered and add " AND user_id:4" (where 4 is the value of the variable containing the current user id) onto the end of it.
