Do you happen to know if that search will distinguish between "Roku 4" and "Roku4"? (I don't want it to -- I'd even want it to give results for "Roku-4" so I can be sure that all renditions of those letters get got.
Tried it myself. A search for Roku 4 yields 50 results. A search for Roku4 yields 29 results. So I can't tell if there are 50 results or as many as 79.
Results are not totally predictable. The method looks usable, though.
A good answer is easier with a clear question giving the make and model of everything. "The biggest problem in communication is the illusion that it has taken place." -- G. “Bernie” Shaw
