Zero to Awesome - Portal Filtering
Portal filtering is simply one of the many tools to be used when you wish to provide an easy path of data access to someone looking for that data. Typically named Clairvoyance or Type Ahead, it's the familiar feature of staring to type and having a larger list of results narrow down based on the addition of new characters. As you type, you find what you're looking for.
While the feature has been possible in earlier versions of FileMaker, via the use of Script Triggering plug-ins, it's now an even more appealing feature with FileMaker 10's built-in Script Triggers.
In this video, I walk through the very detailed specifics of what makes portal filtering work and how you can create/use a reusable script when supporting this feature in multiple places within your FileMaker database.
