Implement a real substring search. It is not possible to place "*substring" search.
This is very annoying not to be able to find topics only because the searched term is started with a prefix (e.g. There is no chance to find a topic about WinCVS jsut by searching for "CVS" or "*CVS".
If it is not possible by default, why it cannot be enabled by some macro or optional plugin?
