• Performing a fuzzy search may retrieve terms with similar spellings: vu sach ty xang x ho. lieu va cao xuc ((va thanh) or (van hanh)) ((vu va) OR (su va)) triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu sach ty xang x ho. lieu va cao xuc ((va thanh) OR (van hanh)) ((vu va) OR (su va)) triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sach ty xang x ho. lieu va cao xuc ((va thanh) or (van hanh)) ((vu va) OR (su va)) triet".
• Adding a wildcard symbol may retrieve word variants: vu sach ty xang x ho. lieu va cao xuc ((va thanh) or (van hanh)) ((vu va) OR (su va)) triet*.
