Why cannot objects be globally searched for in a bucket?
OBS Browser does not support iterative query of objects in a bucket but supports query of objects in a directory only. If you want to search for an object, go to the directory where the object resides and search for the object.
For example, if the root directory of bucket abc contains folder A and object B and folder A contains object C, object C cannot be searched for in the root directory of bucket abc. It can be searched for only in folder A.
