A PDF Document is perfectly searchable
like any other Word Document or an HTML page. To look for a word or
a phrase, select Find from the Edit menu.
In the window that appears on the
screen, enter the word or phrase you want to search for and click
Find.
You
can also check the boxes for any additional choices you might want.
Adobe takes you to the first
occurrence of the word/phrase in your document. If that is the
instance you wanted, click Cancel or else to keep searching,
click Find Next.
