• If you are trying to use Boolean operators, they must be ALL CAPS: (((( te sach menh de gia tuong ) OR ((( tu cach kinh de va cong ) OR ( tu anh kinh de va cong ))))) OR ((( tu dac tinh son gia cuong ) OR ((( tu sac trinh do giam muong ) OR ( tu sac trinh doc gia luong ))))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((( te sach menh de gia tuong ) or ((( tu cach kinh de va cong ) OR ( tu anh kinh de va cong ))))) or ((( tu dac tinh son gia cuong ) or ((( tu sac trinh do giam muong ) or ( tu sac trinh doc gia luong ))))))~".
• Adding a wildcard symbol may retrieve word variants: (((( te sach menh de gia tuong ) or ((( tu cach kinh de va cong ) OR ( tu anh kinh de va cong ))))) or ((( tu dac tinh son gia cuong ) or ((( tu sac trinh do giam muong ) or ( tu sac trinh doc gia luong ))))))*.
