• Performing a fuzzy search may retrieve terms with similar spellings: thuat lanh y nang ma hoi. lieu va cac nuoc ((va dang) OR (va nang)) hai ((cua te) or (cua duc))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuat lanh y nang ma hoi. lieu va cac nuoc ((va dang) OR (va nang)) hai ((cua te) OR (cua duc)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat lanh y nang ma hoi. lieu va cac nuoc ((va dang) OR (va nang)) hai ((cua te) or (cua duc))".
• Adding a wildcard symbol may retrieve word variants: thuat lanh y nang ma hoi. lieu va cac nuoc ((va dang) OR (va nang)) hai ((cua te) or (cua duc))*.
