Library search must be more comfortable

Hello, like described here Library search incorrect I think all the data you see in the Metadata must be also searchable.
So the data like Manufacturer, Lens, focal length and so on will be assign within a list field, and then I can put some parameters I want to search for .
for example
Camera Manufacturer > Nikon
Lens Model> Nikon
focal length>85mm
…so I get all pictures I made with prime Lens like 85/1.8 and 80-200/2.8 where I choose the 85mm

focal length range to choose like 70-105 mm would be nice, but not necessary

Thanks a lot
