This is an example of how to highlight a feature (click on a dot in the application I sent) without doing query maps or anything like that. You're manipulating a layer filter on-the-fly based on your search result. This can work with multiple results but is best suited to just a few results. With more than that you really need to look at some other way to cache features- a queryfile or some sort of a temp table.
Sorry if I've confused things.
