Verity Error - Not letting user search with words NOT,AND,OR, etc. Why??

Question

I've meticulously created collections of the music on my ecommerce music site.  I am manually stripping off offending characters in the submitted search criteria with this code:
Trim(REReplaceNoCase(URLDecode(URL.searchcriteria),"[()<>##""'@]"," ","all"))
Then, if the user has ticked for an "exact word" search, I'm adding double quotes around it, otherwise, leaving it without.  Then submitting it to the right collection for a search with this code (I've substituted ZZZ and XXX for my protection).
<CFSEARCH NAME="ZZZ" COLLECTION="XXX" type="simple" CRITERIA="#cleanedcriteria#" maxrows="300">
When a user does not tick "exact match" but types in any phrase that includes any of the Verity operators, they get the following error:
If you are using type="explicit", you must use Verity Query Language operators such as "<WORD>" or "<STEM>", or surround your search term with quotes. See the documentation for details.
Pass Me Not
will throw the error. but
"Pass Me Not"
which is passed when someone ticks "exact match" does just fine.
From what I've read, the simple search is supposed to assume the <WORD> and <MANY> operators, but it's like that's being ignored.  What am I doing wrong, and/or how can I configure this so that my users can type terms, submit, and find what they're looking for?

Answer 1

I think I finally understand, and am posting the solution here for others' benefit.
Apparently the simple search is in fact behaving properly and will recognize AND OR NOT as operators instead of part of the search string.  The work around for this is to enclose those words in double quotes.  So that's what I've done.  If the user has not specified an "exact match" search (where I enclose the entire string in double quotes), then I single out these three words and put double quotes around them.  It appears to work beautifully.
QED, and am happy to have had a complete uninterrupted discussion with myself.
<cfset cleanedcriteria = ReplaceNoCase(cleanedcriteria,"and","""and""","all")>
<cfset cleanedcriteria = ReplaceNoCase(cleanedcriteria,"not","""not""","all")>
<cfset cleanedcriteria = ReplaceNoCase(cleanedcriteria,"or","""or""","all")>
