• Performing a fuzzy search may retrieve terms with similar spellings: su sac ((ky dang) OR (ky nang)) ha noi. hieu ((van cham) or (va cham)) xuc van hanh vai cua tu~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sac ((ky dang) OR (ky nang)) ha noi. hieu ((van cham) OR (va cham)) xuc van hanh vai cua tu.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sac ((ky dang) OR (ky nang)) ha noi. hieu ((van cham) or (va cham)) xuc van hanh vai cua tu".
• Adding a wildcard symbol may retrieve word variants: su sac ((ky dang) OR (ky nang)) ha noi. hieu ((van cham) or (va cham)) xuc van hanh vai cua tu*.
