"Search" is the correct translation for keres. The course is still in beta, so not every translation is in the database yet. Report it when it comes up again.
Keresem is the definite conjugation, which you only use if the direct object is definite, a certain object, mostly marked with the definite article a. But here it's just any teachers and students you're looking for.
