oh try choosing another search than all files as well. You should have images, documents, audio, video and programmes as well as all types

what do you mean try choosing another search?

Under the "search" magnifiing glass you will see 6 diff selections...laid out in 2 columns of 3. These are to be used to select the type of file you wish to search for, such as Programs, Images, Audio, etc... first click on Images if that is what you will be searching for, then proceed down to the title fill in. This should eliminate most of the other files from interferring with your search.
