• Performing a fuzzy search may retrieve terms with similar spellings: te sach ((ty lang) OR (ty hang)) ha hoi. hieu va co luy gia ((nhanh vi) or (thanh va)) cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((ty lang) OR (ty hang)) ha hoi. hieu va co luy gia ((nhanh vi) OR (thanh va)) cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((ty lang) OR (ty hang)) ha hoi. hieu va co luy gia ((nhanh vi) or (thanh va)) cua tre".
• Adding a wildcard symbol may retrieve word variants: te sach ((ty lang) OR (ty hang)) ha hoi. hieu va co luy gia ((nhanh vi) or (thanh va)) cua tre*.
