• Performing a fuzzy search may retrieve terms with similar spellings: vu ((sach y) or (sach lo)) lang van hoi. hieu ve cam ((xuc va) OR (luc va)) danh di cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu ((sach y) OR (sach lo)) lang van hoi. hieu ve cam ((xuc va) OR (luc va)) danh di cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu ((sach y) or (sach lo)) lang van hoi. hieu ve cam ((xuc va) OR (luc va)) danh di cua tre".
• Adding a wildcard symbol may retrieve word variants: vu ((sach y) or (sach lo)) lang van hoi. hieu ve cam ((xuc va) OR (luc va)) danh di cua tre*.
