Right now when I search on the Gatherer on mobile, either online or in the Companion app, I cannot get it to search for two terms on the same card that are not right next to each other, a functionality I swear it has on PC.

(Using [ text ] to indicate what is typed in the actual field to avoid confusion wrt quote-marks)

For example, if I run a search for [ flying, vigilance ], no matter how I word it, it will only find the 165 cards with flying followed directly by vigilance. It will NOT find the following sample cards I think it ought to:
- Shrike Force (because "flying, double strike, vigilance" apparently doesn't contain the words "flying" and "vigilance" since they aren't adjacent)
- Combat Professor (they only have flying as a keyword, but their other ability mentions vigilance, and therefore it should show up unless I do something specific to make it not do so)
- Odric, Lunarch Marshall and similar cards that care about a listed set of abilities

In short, just plainly typing [ flying, vigilance ] should produce all cards with those two words, while a separate iteration of the terms e.g. [ "flying, vigilance" ] should be required to display only cards on which those words are directly adjacent, perhaps with an intermediate third iteration allowing specifically for the searching of keyword abilities.
