I don't know how keywords work in vrchat but typing the name of the world usually doesn't yield any results.
Thankfully, you can usually search one keyword and get a hit. Next to each world name I put the corresponding keyword.
keywords are not case-sensitive.
Eventually I will add Actual vrchat world IDs for portal/spawn purposes.
