Although there would be a possibility of putting an option in the search of a minimum result size... the best thing to do (for now) would click the SIZE column head twice, thus putting all the small files to the bottom of the search results and the largest at the top (going by your opinion would mean "valid" hits being at the top)

^_^ Stay safe in your searches, always use an anti-virus program to scan programs and EXE files before running them on your computer to aviod naughty programs!
