• Performing a fuzzy search may retrieve terms with similar spellings: te ((sach ty) OR (sach y)) lang xa hoi. hieu ve cac tuc gia ((thanh vi) or (hanh ve)) cau tren~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach ty) OR (sach y)) lang xa hoi. hieu ve cac tuc gia ((thanh vi) OR (hanh ve)) cau tren.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach ty) OR (sach y)) lang xa hoi. hieu ve cac tuc gia ((thanh vi) or (hanh ve)) cau tren".
• Adding a wildcard symbol may retrieve word variants: te ((sach ty) OR (sach y)) lang xa hoi. hieu ve cac tuc gia ((thanh vi) or (hanh ve)) cau tren*.
