enhance search filtration
The combined Search interface is good, but the search filtration system is a bit cumbersome. In general I think one knows whether one is searching for a type/member/property/namespace/method/string etc, and the super-advanced combination filtration system is probably overkill.
I suggest adding a system to allow one to quickly identify the scope of the search within the search box, when the advanced filtration system is more than is needed. Some examples:
member:potato <- searches properties, fields and methods
class:monkey <- only types that are classes
struct:flapjack <- only types that are structs
enum:pancake <- I think you get the idea
These would all be "contains" type searches and would essentially preset the filtration from the search box.
