>> WHERE @city IS NULL OR city LIKE @city <<

I'm not following the logic here.  Let me reword this:

WHERE @passedValueCity IS NULL or dbColumnCity LIKE @passedValueCity

So my new query looks like this:

SELECT listing_id, RANK, name, address, city, zip, heading, phone 
FROM listings a, 
FREETEXTTABLE(listings, *, @Search)
WHERE [KEY] = a.listing_id AND (@passedValueCity IS NULL or dbColumnCity
LIKE @passedValueCity)

I altered my query as such, and it returns no resluts either way - if
passedValue has a value of if it doesn't. (it also doesn't work if I
take off the () around the new AND clause.)

I hope I am making sense.

  WHERE @city IS NULL OR city LIKE @city
