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