How do I search on numerous different values that are in one field? For example, I have a field named "countries" in my database and some cells have four or five values. When I want to search on these after they've been withdrawn from the database I get a URL like this... http://journeys-intl.com/take_out/search_reviews_static.php?country=%Namibia%2C+Botswana%2C+Zimbabwe%2C+South+Africa%
I really do want to search on that many different values but it seems to confuse the db. Is there any way to do this properly?
