• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach ty) OR (sach tu)) xang xa hoi. hieu ((ve cau) OR (va cau)) luc ngan hang vit ca tren.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach ty) or (sach tu)) xang xa hoi. hieu ((ve cau) OR (va cau)) luc ngan hang vit ca tren".
• Adding a wildcard symbol may retrieve word variants: te ((sach ty) or (sach tu)) xang xa hoi. hieu ((ve cau) OR (va cau)) luc ngan hang vit ca tren*.
