Searching forums is not perfect. There are two issues with finding content:
- spelling errors in content
- spelling errors when searching
Allow administrators to define alternative keywords in the ACP, and show a message when a match is found.
In the ACP this would basically look like
Show keyword alternative in search results
xenvoro => xenforo
I'm sure it can be even more advanced, allowing phrases etc. But the basic idea is to remind people they may find more useful content if they simply try an alternative keyword.
