You also have to take into account the trade-offs! In my paper-clips in a jar example, lets say we want to find the string "var foo = bar" you take one clip from the "var" jar, but almost all files has "var" in it ... and there are also many files that has "foo" and "bar" in it! How do you sort the answers from there !? With a simple text/regex search you wouln't have that problem!
