Is there any way to search them?

example:

http://johnnyz86.googlepages.com/HomeWork1.pdf

this is a smaller version of what i want to search, but i cant search
for even the word "and". I can select them with the select tool, so it
is a font, but i cant copy them to notepad to search with that,
because it just shows boxes is there something i can copy it to? any
ideas?
