• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach y nang x ho. ((hieu van) OR (thien van)) ((chat duc) OR (chat doc)) va tinh via cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach y nang x ho. ((hieu van) OR (thien van)) ((chat duc) or (chat doc)) va tinh via cua te".
• Adding a wildcard symbol may retrieve word variants: tu sach y nang x ho. ((hieu van) OR (thien van)) ((chat duc) or (chat doc)) va tinh via cua te*.
