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