If I do this then that MUST contain value1 AND value3. What I want is anything that contains either value1 or value3. Is there a way to do this with the standard filters?
In order for me to use a function I believe I would have to rewrite how that filter works into a function to be used. Or can I append on a custom function onto a filter array? For instance my PercentDone filter works fine but he MC1 is the custom one.
