This is for the NewsBlur Get Satisfaction support site (https://getsatisfaction.com/newsblur/), not NewsBlur itself.
Currently if I enter two or more terms into the Get Satisfaction search box, all items containing one or more of the terms is returned (OR/UNION). This makes it almost impossible to find the right items.
I propose that the Get Satisfaction search box should instead only return items that contains ALL search terms (AND/INTERSECTION). With improved search, I think fewer duplicate items would be created.
