• Performing a fuzzy search may retrieve terms with similar spellings: te sach y ((lang ha) OR (long ha)) hoi. hieu van lam xuc va danh vai ((cau tren) or (dau tren))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y ((lang ha) OR (long ha)) hoi. hieu van lam xuc va danh vai ((cau tren) OR (dau tren)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y ((lang ha) OR (long ha)) hoi. hieu van lam xuc va danh vai ((cau tren) or (dau tren))".
• Adding a wildcard symbol may retrieve word variants: te sach y ((lang ha) OR (long ha)) hoi. hieu van lam xuc va danh vai ((cau tren) or (dau tren))*.
