These 'might' help (a)
Problems with the search,
__ (b)
Hostiles List.
But it's not uncommon that on occasions sometimes searches come a blank. It may mean some ultrapeers you are connected to are not responding properly. I'm not sure. It happens to me sometimes too. When that happens, I search for something else, or try again in 30-60+ mins later.
There is an option to remove an ultrapeer & see if that helps.
