      Description

      I have a collection that has 'nested' documents. For example, a document can have the following structure:

      {
          "condition": {
              "parameter": {
                  "type": "person"
              }
          }
      }
      

      as well as:

      {
          "condition": {
              "conditions": [
                  {
                      "conditions": [
                          {
                              "parameter": {
                                  "type": "A"
                              }
                          },
                          {
                              "parameter": {
                                  "type": "B"
                              }
                          }
                      ]
                  },
                  {
                      "parameter": {
                          "type": "C"
                      }
                  }
              ]
          }
      }
      

      Meaning, each condition sub-document can have multiple conditions within itself.

      Now, I'd want to make a 'recursive' query on the type field of each condition, something like ('..' representing the recursion):

      {
          "$or": [
              {"condition.type": "person"},
              {"condition..conditions.type": "person"}
          ]
      }
      

      From what I've seen there's no way to do this yet, but it would be really awesome.
