TOPIC:

I have used the sample application comes with the sdk in which the search is working fine. I am making a POC so I tried integrating Radaee pdf with my POC application. The search functionality is not working now. It always shows a toast message like "no more found". Is this a licensing issue? kindly clarify on this

It seems you're not activating the license.
I suspect your app has an application package name different from our demo project.

Without license activation, text search and extraction shall return false.
