• Performing a fuzzy search may retrieve terms with similar spellings: tu sac ky nang ma hoi. ((((lieu van) OR (hieu van))) or (lieu va)) cao quoc ban benh va chua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky nang ma hoi. ((((lieu van) OR (hieu van))) OR (lieu va)) cao quoc ban benh va chua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky nang ma hoi. ((((lieu van) OR (hieu van))) or (lieu va)) cao quoc ban benh va chua tre".
• Adding a wildcard symbol may retrieve word variants: tu sac ky nang ma hoi. ((((lieu van) OR (hieu van))) or (lieu va)) cao quoc ban benh va chua tre*.
