Is there any way of making the search results from a file search appear in a window? (essentially, like searching in windows 7)

Often I search for a number of files in different locations and I have to keep re-searching the same term over and over again until I find what I'm looking for, because onnce one file is opened or its location is opened, the search results disappear.

Alternatively, is there a search program that can be used instead of windows search that works like windows 7 (without being extremely slow like one program I tried)?

many thanks
