Update PageFinder to support altOperators in selectors. This enables you to use more than one operator in a selector. For example, if you wanted to first try to find pages matching a phrase (*=), and if it doesn't find any, fallback to find pages matching words (~=), you can just append the two opers together. i.e. "field*=~=value". This works for any operator combinations and you can stack as many as you need.
