• Performing a fuzzy search may retrieve terms with similar spellings: tu sac ky nang ((o hoi) or (o hai)). hieu va hau xuc ban ban ((thai cua) OR (than cua)) te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky nang ((o hoi) OR (o hai)). hieu va hau xuc ban ban ((thai cua) OR (than cua)) te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky nang ((o hoi) or (o hai)). hieu va hau xuc ban ban ((thai cua) OR (than cua)) te".
• Adding a wildcard symbol may retrieve word variants: tu sac ky nang ((o hoi) or (o hai)). hieu va hau xuc ban ban ((thai cua) OR (than cua)) te*.
