• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ky dang ((van hoi) OR (van hoc)). lieu va cam ((luc va) or (tuc va)) hang tai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ky dang ((van hoi) OR (van hoc)). lieu va cam ((luc va) OR (tuc va)) hang tai cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ky dang ((van hoi) OR (van hoc)). lieu va cam ((luc va) or (tuc va)) hang tai cua tre".
