• Performing a fuzzy search may retrieve terms with similar spellings: su sach y dang ha hoi. thien van cam ((xuc va) or (tuc va)) ((thanh di) OR (thanh do)) cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach y dang ha hoi. thien van cam ((xuc va) OR (tuc va)) ((thanh di) OR (thanh do)) cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach y dang ha hoi. thien van cam ((xuc va) or (tuc va)) ((thanh di) OR (thanh do)) cua tre".
