• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ty hoang van hoc. hieu ((van dat) OR (dan dat)) (nuoc OR duoc) va tinh vi cua tu*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ty hoang van hoc. hieu ((van dat) or (dan dat)) (nuoc OR duoc) va tinh vi cua tu*".
