• Performing a fuzzy search may retrieve terms with similar spellings: tu sach y lang xa hoi. ((nhieu viec) OR (nhien viet)) cua ((xuc va) or (thuc va)) tinh de cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach y lang xa hoi. ((nhieu viec) OR (nhien viet)) cua ((xuc va) OR (thuc va)) tinh de cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach y lang xa hoi. ((nhieu viec) OR (nhien viet)) cua ((xuc va) or (thuc va)) tinh de cua tre*".
