• Performing a fuzzy search may retrieve terms with similar spellings: vu sach ty hang ha hoi. hieu ((((van cam) OR (van dam))) or (van nam)) loc va thanh vi cau treo~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu sach ty hang ha hoi. hieu ((((van cam) OR (van dam))) OR (van nam)) loc va thanh vi cau treo.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sach ty hang ha hoi. hieu ((((van cam) OR (van dam))) or (van nam)) loc va thanh vi cau treo".
• Adding a wildcard symbol may retrieve word variants: vu sach ty hang ha hoi. hieu ((((van cam) OR (van dam))) or (van nam)) loc va thanh vi cau treo*.
