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