• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sac) OR (su sach)) ky tang tai hoi. thien van cam xuc ban hang ((dan cua) OR (ban cua)) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sac) OR (su sach)) ky tang tai hoi. thien van cam xuc ban hang ((dan cua) or (ban cua)) tre".
• Adding a wildcard symbol may retrieve word variants: ((su sac) OR (su sach)) ky tang tai hoi. thien van cam xuc ban hang ((dan cua) or (ban cua)) tre*.
