• Performing a fuzzy search may retrieve terms with similar spellings: tu dan ky nang mai hoi. lieu ((va nay) OR (va cay)) ((thuc xa) or (thuc va)) hanh tai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu dan ky nang mai hoi. lieu ((va nay) OR (va cay)) ((thuc xa) OR (thuc va)) hanh tai cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu dan ky nang mai hoi. lieu ((va nay) OR (va cay)) ((thuc xa) or (thuc va)) hanh tai cua tre".
• Adding a wildcard symbol may retrieve word variants: tu dan ky nang mai hoi. lieu ((va nay) OR (va cay)) ((thuc xa) or (thuc va)) hanh tai cua tre*.
