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