Concern: someone could pick observant feat to get investigation expertise they could not use for search as a bonus action, since UA did not include investigation skill as a part of the search action.
for keen mind, they can also pick expertise in investigation and study is a valid option for investigation
my concern suggestion:
a. Make investigation valid for search or study actions
b. If not valid for search, remove it from observant instead to reduce confusion
