• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ty xang xa hoi. hieu ve cac xuc ((va tinh) OR (ban hanh)) ((vai cua) OR (hai cua)) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty xang xa hoi. hieu ve cac xuc ((va tinh) or (ban hanh)) ((vai cua) OR (hai cua)) tre".
• Adding a wildcard symbol may retrieve word variants: te sach ty xang xa hoi. hieu ve cac xuc ((va tinh) or (ban hanh)) ((vai cua) OR (hai cua)) tre*.
