On the advanced card search engine there is a feature that allows the user to narrow their search by card colours. There are three options on how the user can limit their search around colours: include, exclude, and exactly. The "exactly" option does not work as read; it functions identically to the "include" option. "Exactly" entails that what ever colour(s) I select to search by is the only colour(s) of cards that should be presented to me. For example, if I do a search for [(card type>creatures) + (colour > exactly > red)] then I should be provided a list of cards that strictly reflects those specifications: red creatures. Instead, the "exactly" option functions as "include" in that when I search for the same thing (red creatures) I am provided a list of creatures that include red but may have other colours in the mana cost (e.g., a blue-red creature).
