replace exact string only

I'm outputting text content to my page by querying our database using a simple method, which works fine.
quote:

<cfoutput query="getPageContent" startrow="#vPageContent#" maxrows="1">#vContent#</cfoutput>

I need to replace certain words to make them bold, for example...
quote:

<cfset request.vContent = replace(request.vContent, "phrase", "<B>phrase</B>, "ALL")>

This works, but there is a slight issue, because it will also replace occurances of the word 'phrase' even if it is within another word...

for example, co phrasetastic

So i need to replace only the exact phrase when used on it's own.

My problem appears quite simple, but I have not found a way to do this...?

    note the spaces in the following:

    <cfset request.vContent=replace(request.vContent," phrase "," phrase
    ","ALL")>

    or use regex via the reReplace method with something like the "transition
    boundary" escape sequence "\b" (check the syntax, doing this from poor memory):
    reReplace(vContent,"\bphrase\b"," phrase","ALL")
