Claude's last suggestion. However, distinguishing between a 'word' and a
'phrase', without knowing what constitutes a phrase (that is, wihout
already having a dictionary of what you want to consider to be phrases) is
going to be difficult or impossible.
To answer your question... yes. You'd first put together a keyword list
and then remove duplicates of those keywords from your string. But from
the sounds of what you're trying to do, once you've put together the
keyword list you're finished.
Try this:
<cfset s = "A string, or maybe not a string. Who knows? And who cares?">
<cfset keywords = "">
<cfloop index="w" list="#s#" delimiters=" .,?!;:%$&""'/|[]{}()">
<cfif not ListFindNoCase(keywords, w)>
<cfset keywords = ListAppend(keywords, LCase(w))>
</cfif>
</cfloop>
<cfoutput>
<pre>
s: #s#
keywords: #keywords#
</pre>
</cfoutput>
