• Performing a fuzzy search may retrieve terms with similar spellings: te sach yu hang va hoa. hieu ve cac ((xuc van) or (luc van)) ((hanh ke) OR (hanh ky)) cau treo~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach yu hang va hoa. hieu ve cac ((xuc van) OR (luc van)) ((hanh ke) OR (hanh ky)) cau treo.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach yu hang va hoa. hieu ve cac ((xuc van) or (luc van)) ((hanh ke) OR (hanh ky)) cau treo".
• Adding a wildcard symbol may retrieve word variants: te sach yu hang va hoa. hieu ve cac ((xuc van) or (luc van)) ((hanh ke) OR (hanh ky)) cau treo*.
