Is there any way to implement roku search inside my channel like a button inside my channel that utilizes roku search to search content inside my channel.
as far as we know global roku search will search across all platforms and return results from all platforms including yours if you are participating in the roku <<not sure the official name >> search program
for search within your app only, I am pretty sure Roku will not help you and you have to write your own custom search apis and query them for your data and also how you want it presented, in what order etc, that's totally up to you and how you code that on your back end ... as to what order the data appears on your front end
