• Performing a fuzzy search may retrieve terms with similar spellings: thuat sach ty nang cao hoi. hieu su ((cham o) or (cam lo)) va tinh vai ((cau treo) OR (cau theo))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuat sach ty nang cao hoi. hieu su ((cham o) OR (cam lo)) va tinh vai ((cau treo) OR (cau theo)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat sach ty nang cao hoi. hieu su ((cham o) or (cam lo)) va tinh vai ((cau treo) OR (cau theo))".
• Adding a wildcard symbol may retrieve word variants: thuat sach ty nang cao hoi. hieu su ((cham o) or (cam lo)) va tinh vai ((cau treo) OR (cau theo))*.
