Index -> Interface -> Filters & Search Options
While using the Deck Builder or Collection Manager, or while engaging in Trade with another player, you may wish to search for a specific card, browse for cards of a certain race, or maybe search for cards with a certain word or phrase in their title or text. To do this, use the Filters & Search options located in the lower-left corner of the screen.
