• If you are trying to use Boolean operators, they must be ALL CAPS: te sach va nang xa hoi. hieu van ((huu loc) OR (hau loc)) van ((hanh dieu) OR (han dieu)) cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach va nang xa hoi. hieu van ((huu loc) OR (hau loc)) van ((hanh dieu) or (han dieu)) cua tre".
• Adding a wildcard symbol may retrieve word variants: te sach va nang xa hoi. hieu van ((huu loc) OR (hau loc)) van ((hanh dieu) or (han dieu)) cua tre*.
