Simple? Searching for multiple values in one field

I’d like to search for contacts in an area of multiple cities. I’ve tried to use City “equals” and City “contains” and drop in a comma delimited list of cities, but it finds no one, although we do have contacts who live in those cities. Is there a special syntax I should be using?

The field type will determine a lot in terms of what you’re searching and how. In the case of City, it’s a text field. Text fields cannot use multiple searches in decision diamonds.
