When I enter "device sync error" as search terms, the forum software replies:
"The following words in your search query were ignored because they are too common words: device error sync. You must specify at least one word to search for. Each word must consist of at least 3 characters and must not contain more than 14 characters excluding wildcards."
I should think these terms should make a valid search. Perhaps the forum search admin settings need to be tweaked a bit.
