• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y lang ha hoi. hieu va ((co luc) OR (coc luc)) gia ((nhanh vi) OR (thanh va)) cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y lang ha hoi. hieu va ((co luc) OR (coc luc)) gia ((nhanh vi) or (thanh va)) cua tre".
• Adding a wildcard symbol may retrieve word variants: te sach y lang ha hoi. hieu va ((co luc) OR (coc luc)) gia ((nhanh vi) or (thanh va)) cua tre*.
