• Performing a fuzzy search may retrieve terms with similar spellings: thuat sach thi hanh xa hoi. hieu ((ve cam) or (va cam)) tuc van hanh lam ((va triet) OR (va thiet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuat sach thi hanh xa hoi. hieu ((ve cam) OR (va cam)) tuc van hanh lam ((va triet) OR (va thiet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat sach thi hanh xa hoi. hieu ((ve cam) or (va cam)) tuc van hanh lam ((va triet) OR (va thiet))".
• Adding a wildcard symbol may retrieve word variants: thuat sach thi hanh xa hoi. hieu ((ve cam) or (va cam)) tuc van hanh lam ((va triet) OR (va thiet))*.
