I've been using Eclipse Ganymede (Version: 3.4.2) Search > File Search a lot...works great...except...
Say you want two files (two tabs) in the edit window. You search for the first one, get a few hits, click 'Show Next Match' a few times, each file showing using the same window in the edit pane (reusing the edit window). In this case, reusing the same edit window is good.
Now you have found the first file you're looking for, it's open in the editor, and you go to Search > File Search again and put in the search criteria for the second file.
As soon as you click 'Show Next Match', the file you opened earlier is _gone_ with no apparent way to get it open again without searching for it again!
I know I can make a 'fake edit' to the file, and that edit window will not be reused when I click 'Show Next Match', but I don't like to make fake edits because then I have to wonder if I really changed something there.
