Yep, the constraint filter function is the best for you. forget about the search its a little to long and complex.
Can't find it ? Do this : Under the View menu (Yes the one on top between Edit and Insert) So, View + Commands list + ConstraintFilter. You'll have a little window to hide all constraint or more...
There's no icon for this function, create one (that's what I did) using Tools+Customize+Commands.
Take Care, cause this will hide ALL constraint sketcher constraint, Assy const... So don't forget about this function if you are in sketcher mode and couldn't see your dimensions.
Hope this help!
