Running a PlanetLab-wide search is not supported with the web GUI, but it is supported on the commandline. The only difference in this case is that we do not specify the sensor we are looking for (i.e., the node iP address) in the list of options. By getting the commandline for a search pertaining to a particular node, and by eliminating the mention of the sensor, one can execute a PL-wide search. Searches of this type will take between a few minutes to a the greater part of an hour, depending on the duration of the search.
