• Performing a fuzzy search may retrieve terms with similar spellings: te sach ty hang ca hoi. lieu va cam thu vat ((((danh vai) OR (dang van))) or (danh sai)) cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ty hang ca hoi. lieu va cam thu vat ((((danh vai) OR (dang van))) OR (danh sai)) cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty hang ca hoi. lieu va cam thu vat ((((danh vai) OR (dang van))) or (danh sai)) cuu tre".
• Adding a wildcard symbol may retrieve word variants: te sach ty hang ca hoi. lieu va cam thu vat ((((danh vai) OR (dang van))) or (danh sai)) cuu tre*.
