• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ty nang x hoi. hieu ve cham ((xuc van) OR (xuc ban)) anh di ((cua triet) or (cau tren))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ty nang x hoi. hieu ve cham ((xuc van) OR (xuc ban)) anh di ((cua triet) OR (cau tren)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ty nang x hoi. hieu ve cham ((xuc van) OR (xuc ban)) anh di ((cua triet) or (cau tren))".
• Adding a wildcard symbol may retrieve word variants: tu sach ty nang x hoi. hieu ve cham ((xuc van) OR (xuc ban)) anh di ((cua triet) or (cau tren))*.
