• If you are trying to use Boolean operators, they must be ALL CAPS: vu ((sach ly) OR (((sach hoi) OR (sach doi)))) lang van hoi. hieu ve cac tac ca dan de cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu ((sach ly) or (((sach hoi) OR (sach doi)))) lang van hoi. hieu ve cac tac ca dan de cua tre~".
• Adding a wildcard symbol may retrieve word variants: vu ((sach ly) or (((sach hoi) OR (sach doi)))) lang van hoi. hieu ve cac tac ca dan de cua tre*.
