Step 1: Install the userscript with a violentmonkey, tampermonkey, or any other favorite userscripts manager. Step 2: Refresh the 8chan page if you're already on it. Open the javascript console. Step 3: `searchInThreads('<WHAT I WANT TO SEARCH HERE>')` Wait until you get the green "Search completed." message.
