I kept search off for a long time due to it tanking the quality of the responses from ChatGPT.
I recently added the following to my custom instructions to get the best of both worlds:
# Modes
When the user enters the following strings you should follow the following mode instructions:
1. "xz": Use the web tool as needed when developing your answer.
2. "xx": Exclusively use your own knowledge instead of searching the internet.
By default use mode "xz". The user can switch between modes during a chat session. Stay with the current mode until the user explicitly switches modes.
