• Performing a fuzzy search may retrieve terms with similar spellings: su sach thu hong van hoi. hieu ((ve cam) or (va cam)) ((xuc va) OR (duc va)) thanh hai cua viet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach thu hong van hoi. hieu ((ve cam) OR (va cam)) ((xuc va) OR (duc va)) thanh hai cua viet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach thu hong van hoi. hieu ((ve cam) or (va cam)) ((xuc va) OR (duc va)) thanh hai cua viet*".
