+
+Vim has two ways to find matches for a pattern: Internal and external.  The
+advantage of the internal grep is that it works on all systems and uses the
+powerful Vim search patterns.  An external grep program can be used when the
+Vim grep does not do what you want.
+
+The internal method may be a bit slower, because files are read into memory.
+The advantage is that line separators and encoding are automatically
+recognized, as if a file is being edited.  And multi-line patterns can be
+used.

 Vim can interface with "grep" and grep-like programs (such as the GNU
 id-utils) in a similar way to its compiler integration (see |:make| above).

-5.3 Browsing source code with :grep
+5.5 Browsing source code with :vimgrep or :grep
 
 Using the stack of error lists that Vim keeps, you can browse your files to
 look for functions and the functions they call.  For example, suppose that you
 have to add an argument to the read_file() function.  You enter this command: >
 
-	:grep read_file *.c
+	:vimgrep /\<read_file\>/ *.c
 
 You use ":cn" to go along the list of matches and add the argument.  At one
 place you have to get the new argument from a higher level function msg(), and
 need to change that one too.  Thus you use: >
 
-	:grep msg *.c
+	:vimgrep /\<msg\>/ *.c
 
 While changing the msg() functions, you find another function that needs to
-get the argument from a higher level.  You can again use ":grep" to find these
-functions.  Once you are finished with one function, you can use >
