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