• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ((y nang) OR (ly nang)) mai hoi. lieu va cam tu xa hanh ((vi cua) OR (vai cua)) tu.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ((y nang) OR (ly nang)) mai hoi. lieu va cam tu xa hanh ((vi cua) or (vai cua)) tu".
• Adding a wildcard symbol may retrieve word variants: thu sach ((y nang) OR (ly nang)) mai hoi. lieu va cam tu xa hanh ((vi cua) or (vai cua)) tu*.
