Use PiPointlist.FilteredSummaries with FilterExpression to get tags that have at least one good value?

We have about 3500 PiPoints that we want to get summaries from. However, for the given time range, the majority of the points have no good values, so we figured we'd write a filter expression to exclude all those points and only return summaries for those points that have good values.


Is this doable, and if so, how?


On a more general note, are there any good tutorials/guides on using filter expressions with the AF SDK? I'm completely new to the filter expressions, and I'm having trouble finding a good guide or introduction.


Thanks in advance for all help!
