Card search needs vast improvements! (on Arena Android if that matters)

With the addition of MH3, which has a substantial number of cards that interact with energy counters.
If I'm wanting to search the Historic card pool for cards to build an energy-focused deck, how am I able to do that? Slowly side scroll through the entire Historic card pool?
Searching "energy" pulls up 3 cards with the word energy in its text.

This highlights a huge issue with trying to deck build on Arena. You are not able to search with nearly enough specificity.

Say I want to build a deck that is focused on a specific power and higher, a specific counter that is only indicated by an icon, or any of the other indicators that aren't color, cost, or type, how do I search those?

There are a lot of third party apps or websites that allow much more detailed searching, I can't see it as being that difficult to identify those specifics that are lacking and add them to the available search criteria.
