title: Keyword Search in the Khan Academy API
body: <p>I am using Khan Academy API to get topics, exercises and videos. I want a basic "search by keyword" feature through the API, where a user can type a keyword and the app displays a list of topics, exercises and videos containing that keyword. But, I'm finding that almost impossible as the API officially lacks features like keyword search and pagination.</p>
  
  <p>I was doing a lot of research to find more documentation on how to do it to no avail.
  Please help me do this.</p>
