• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (thu sach)) ly nang xa hoi. hieu ve cham luc vay doan ((van cua) OR (vang cua)) tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) or (thu sach)) ly nang xa hoi. hieu ve cham luc vay doan ((van cua) OR (vang cua)) tre~".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) or (thu sach)) ly nang xa hoi. hieu ve cham luc vay doan ((van cua) OR (vang cua)) tre*.
