Expand Ash.Query.Operator built_in operators

Right now, ash comes with a bunch of built-in operator for queries (

is_nil

is_nil

eq

eq

in

in

less_than

less_than

, etc).

These are great, but it is not enough in some cases. For example, let's say I want to create a

similarity

similarity

operator?

The obvious answer is that I can implement it myself using the

Ash.Query.Operator.__using__/1

Ash.Query.Operator.__using__/1

macro.

The problem with that is that I can't see how to make these new operators available globally for my resources.

For example, if we look in

AshGraphql

AshGraphql

, the

resource.ex

resource.ex

file will create the filters based in the built-in filters using the

Ash.Filter.builtin_operators()

Ash.Filter.builtin_operators()

inside the

filter_type

filter_type

function. AFAIK there is no way to expand the built-in operators with a custom one, to make the

Ash.Filter.builtin_operators()

Ash.Filter.builtin_operators()

return also my custom operators, or, specifically for

AshGraphql

AshGraphql

make the

filter_type

filter_type

function also fetch my custom operators.

Is there a workaround for that that I'm not aware? And if not, is that something that is planned?
