Match patterns/specs are a difficult DSL. Have you looked at GitHub - ericmj/ex2ms: :ets.fun2ms for Elixir, translate functions to match specifications · GitHub?

Yes, I have, that’s where I started 
but I am not at all clear how to make a key search and I think that’s the main issue here.

Afaik there is no special keysearch in ets. If you want to sesrch by key search by the first tuple element of items in the ets table.

Ahhhh, thanks for that. I did not work out that {k, v} nature of the select construction. All good now, thanks.

Well, ETS does not need to be 2 element tuples with the key beeing the first element… When you create the table with :ets.new/2, you can specify the position of the key using the :keypos option.
You can then use :ets.lookup/2 to lookup all entries that have match your key.
