Discord is a chat program. Chat comes and goes. The fact that search sucks is a feature. If you need a good search feature, good categorisation, etc then you need a forum or something similar. People use Discord because they don't want a forum, they want a chat.
Most information, especially anything about video games, is tucked away in a discord nowadays. I'm in many that literally act as storage of information - a large number of channels that only the admin can post in where they post info.
