• Performing a fuzzy search may retrieve terms with similar spellings: ((tu cao) or (vu cao)) ky nang mai hoi. hieu ((ve cham) OR (vu cham)) tuc va thanh vi cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu cao) OR (vu cao)) ky nang mai hoi. hieu ((ve cham) OR (vu cham)) tuc va thanh vi cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu cao) or (vu cao)) ky nang mai hoi. hieu ((ve cham) OR (vu cham)) tuc va thanh vi cua tre*".
