• If you are trying to use Boolean operators, they must be ALL CAPS: ((((proa OR prot) OR (proud OR profud)) OR ((prol OR prof) OR peron)) OR pro){acute}actica ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((proa or prot) or (proud or profud)) or ((prol OR prof) or peron)) or pro){acute}actica ;*".
