我正在尝试更多地了解 RethinkDB 及其子查询功能。我想知道在 ReThinkDB 中是否可以进行以下操作:

// example of "post" document:
{ id: .., allow: [], disallow: [some_label_id, other_label_id], ... }

// example of "label" document:
{ id: .., user_id: .., name: 'my-label' }

var MY_USER_ID = "1b4-4c6-7d9"

// Query in psuedo-code:
IN database test
IN table posts   
FILTER out any "posts" where the "disallow" array
  contains a value found in this sub-query:
   IN table labels  
   FILTER id .eq disallow[index] AND user_id .eq MY_USER_ID

RethinkDB 目前没有intersectcontains命令。它们将在暂定于 4 月 15 日发布的 1.4 版本中。
