• Performing a fuzzy search may retrieve terms with similar spellings: su sach ly hang xa hoi. hieu vu ((cham luu) or (phap luu)) van hanh vi ((su triet) OR (ve triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ly hang xa hoi. hieu vu ((cham luu) OR (phap luu)) van hanh vi ((su triet) OR (ve triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ly hang xa hoi. hieu vu ((cham luu) or (phap luu)) van hanh vi ((su triet) OR (ve triet))".
• Adding a wildcard symbol may retrieve word variants: su sach ly hang xa hoi. hieu vu ((cham luu) or (phap luu)) van hanh vi ((su triet) OR (ve triet))*.
