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