Index on additional fields in many-to-many link

[dimyy]

How to add index on additional field in many-to-many link? For example on field "role" in account-to-contact link?

I try add Index: true to additionalColumns in link description. Nothing happens.

    "links": {
        "accounts": {
            "additionalColumns": {
                "role": {
                    "index":true
                }
            }
        },

This should work I believe:

​
    "links": {
        "accounts": {
            "additionalColumns": {
                "role": {
                    "type": "varchar"
                }
            },
            "indexes": {
                "role": {
                    "columns": ["role"]
                }
            }
        }
    }​
