• If you are trying to use Boolean operators, they must be ALL CAPS: ((vu sach) OR (su sach)) ty hang xa hoi. thien van bac duc va danh ((thai cuu) OR (thi cuc)) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((vu sach) or (su sach)) ty hang xa hoi. thien van bac duc va danh ((thai cuu) OR (thi cuc)) tre".
• Adding a wildcard symbol may retrieve word variants: ((vu sach) or (su sach)) ty hang xa hoi. thien van bac duc va danh ((thai cuu) OR (thi cuc)) tre*.
