This is exactly the feature my client needs. They use the tags and the categories but need to also select by a sector. This would be an option tick box custom field for the articles. Then you could search by
tag and or custom field and or date the or being if all was selected against any of the others so its not part of the refinement.
Can I also say how good this product is. We will be featuring it at our next JUG as I think it and a lot of the other minitek products look so polished and professional
