Here is the method I normally use to count words:

tr A-Z a-z | tr -cs -a-z0-9\'\" '\012' | sort -u | wc -l

The first "tr" command take care of capitalization.  The second "tr" command
separates the file into a word per line (where a word is a sequence of
characters [-A-Za-z0-9'"]).  The "sort" command eliminates duplicates and
the "wc" gives us the number of lines in the result.
