Search by Encounter.mediaAsset field

What Wildbook should this feature be in?
Flukebook (and possibly helpful in others too, but Flukebook is the only one I use)

What would you like to see?
I want to be able to search my encounters based on the Encounter.mediaAsset field.

How would this functionality help you?
I want to be able to index my data in Flukebook in a way that allows me to readily search/query for an individual photo in my dataset on Flukebook (e.g. if I want to go back and double check the match proposed for a specific encounter/photo, or export results from a specific set of photos).
