• If you are trying to use Boolean operators, they must be ALL CAPS: vu sach ty ((((nang xa) OR (lang xa))) OR (sang ma)) hoi. hieu ve cham duc va hanh doi cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sach ty ((((nang xa) OR (lang xa))) or (sang ma)) hoi. hieu ve cham duc va hanh doi cua tre".
• Adding a wildcard symbol may retrieve word variants: vu sach ty ((((nang xa) OR (lang xa))) or (sang ma)) hoi. hieu ve cham duc va hanh doi cua tre*.
