The Keyword Search Engine infers queries based on the keywords you enter in the search bar.
This means that for example you can search your users by just typing their email addresses in the Search bar. firstname.lastname@example.org will return the user matching that email address. Searching @apple.com will return all users with an apple.com email address.
Similarly, typing a8641ae2e2181300d4790e3b will return any field that has this ObjectID as value.
