Dear Web,

The following should do the trick, searching for the word "machine" either
at the beginning of a line and followed by a space, surrounded by spaces, or
preceded by a space and at the end of a line. Type the following (not the
bit with the dashes, though):

M-x re-search-forward RET
\(^\|[ \t]\)machine\([ \t]\|$\)

It's probably more constructive to copy the regexp than to type it all in.
This will place your cursor at the *end* of whatever it finds.

For more information, the section in the Info system on regexps is useful.
