The symbol ` is for command substitution.... it takes the output of the
command within, and uses that as options for the other command.
Sort of like a pipe, but different.
So, to answer your question:
cat `find . -name filespec` | grep something
will find files in the current directory (and its subdirectories)
with names matching "filespec", cat each file in turn,
and search each file for "something".
