• Performing a fuzzy search may retrieve terms with similar spellings: ((tu sac) OR (tu sach)) ky lang xa hoi. hieu dien ban duoc gia ((thanh vi) or (thanh ve)) cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sac) OR (tu sach)) ky lang xa hoi. hieu dien ban duoc gia ((thanh vi) OR (thanh ve)) cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sac) OR (tu sach)) ky lang xa hoi. hieu dien ban duoc gia ((thanh vi) or (thanh ve)) cua tre".
• Adding a wildcard symbol may retrieve word variants: ((tu sac) OR (tu sach)) ky lang xa hoi. hieu dien ban duoc gia ((thanh vi) or (thanh ve)) cua tre*.
