How do you turn on safe search filter?

How do you turn off search filter in Windows 7? NOT the internet one?

• I AM NOT TALKING ABOUT INTERNET SEARCH. I AM TALKING ABOUT SEARCHING THE COMPUTER FOR A FILE. I've spent the last half hour trying to figure out how to locate a certain file on my computer called "The End". When I type it into the search box, it changes the word "end" into some kind of date filter, and searches for all files with "the" in them. It's a text file, and I remember some of the content, but I can only find ways to search for part of the NAME of the file. Is there a way to either turn off the automatic search filter or search for text in the file instead of the name?

• Answer:
