If you want to highlight it only temporarily you may want to try
highlight-regexp:

C-x w h runs the command highlight-regexp
   which is an alias for `hi-lock-face-buffer' in `hi-lock'.
(highlight-regexp REGEXP &optional FACE)

Set face of each match of REGEXP to FACE.

Interactively, prompt for REGEXP then FACE.  Buffer-local history
list maintained for regexps, global history maintained for faces.
Use M-n and M-p to retrieve next or previous history item.
(See info node `Minibuffer History')

or highlight-phrase:

C-x w p runs the command highlight-phrase
   which is an alias for `hi-lock-face-phrase-buffer' in `hi-lock'.
(highlight-phrase REGEXP &optional FACE)

Set face of each match of phrase REGEXP to FACE.

Whitespace in REGEXP converted to arbitrary whitespace and initial
lower-case letters made case insensitive.

These are in my Edit menu also.
