Windows search disregarding spaces

I am trying to find files that contain " - 1", however, Windows will strip the spaces and fins all files that contain "-1". I have well over 100,000 files with "-1" in them, but very few files with " - 1" in the filename. I really need to find these files.

Is there any way to force Windows to search for what I typed rather than what it "thinks" I am looking for??

I know the " - 1" vs "-1" question is strange. These are files autogenerated by two different programs into the same directory and this is the only difference between their naming schemes.
