• If you are trying to use Boolean operators, they must be ALL CAPS: (((( tu ((sach menh) OR (sach kinh)) de giau cuong ) OR ((( tu sac tinh cao gia cong ) OR ( tu sac tinh dau gia cuong ))))) OR ( tu may ((tinh doi) OR (tinh hoc)) giam muong ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((( tu ((sach menh) or (sach kinh)) de giau cuong ) or ((( tu sac tinh cao gia cong ) or ( tu sac tinh dau gia cuong ))))) or ( tu may ((tinh doi) OR (tinh hoc)) giam muong ))~".
• Adding a wildcard symbol may retrieve word variants: (((( tu ((sach menh) or (sach kinh)) de giau cuong ) or ((( tu sac tinh cao gia cong ) or ( tu sac tinh dau gia cuong ))))) or ( tu may ((tinh doi) OR (tinh hoc)) giam muong ))*.
