• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ((ty nang) OR (ky nang)) cao hoi. ((hieu ve) OR (lieu va)) cam lo va danh via cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ((ty nang) OR (ky nang)) cao hoi. ((hieu ve) or (lieu va)) cam lo va danh via cua te".
• Adding a wildcard symbol may retrieve word variants: tu sach ((ty nang) OR (ky nang)) cao hoi. ((hieu ve) or (lieu va)) cam lo va danh via cua te*.
