Thanks. You said two examples. Was this the single search [bsi +lnk scada +foof things i will not] or two different searches? Usually we write [X] or ["X Y"] to mean doing a search for X or "X Y" at Google, so adding square brackets would help me understand what the two searches were more clearly.

Or were you just frustrated that we assumed "foof" was intended to be "food" unless you added the '+' character to specify an exact match?
