Search: Auto shut off based on server load?

[kontrabass]

Would it be possible to implement a feature, where the search is automatically shut off if the server load reaches a preset number? This would be a great "buffer", so that maybe the "Server load too high" messages would be less frequent.

I've got a bit of a load problem, and if a lot of people search when the server load is already high, it skyrockets and then users get the "server too busy" error (I set the load at 6 in my CP).

Thanks!
