To search on IPTV using a Firestick remote, start by opening the IPTV app on your Firestick device. Navigate to the search function within the app using the directional buttons on the remote. Once you've selected the search option, a virtual keyboard will appear on your screen.

Using the directional buttons, move the cursor to select each letter of your search query. Press the select button on the remote to input each letter. If your Firestick remote supports voice input, you can also use the microphone button to speak your search query.

Once you've entered your full search query, navigate to the search or submit button on the virtual keyboard using the directional buttons. Press the select button to initiate the search process.

The IPTV app will then display search results matching your query. You can browse through the results using the directional buttons and select the desired content to start streaming.
