From the docs:

The example search starting callback in Example Search Starting Callback adds either morning or afternoon to the query depending on the time of day.

A callback is a function that gets called at a later point in time, for example when the user of the website takes some action. In this case, the callback gets called when the user enters a search query, and this callback modifies the search query to add either "morning" or "afternoon" to the end of that search depending on the user's current time.
