• If you are trying to use Boolean operators, they must be ALL CAPS: ((doc sach) OR (toc sach)) dao hang xa hoi. hieu ((va chat) OR (van chat)) xuc van danh di cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((doc sach) or (toc sach)) dao hang xa hoi. hieu ((va chat) OR (van chat)) xuc van danh di cua tre~".
• Adding a wildcard symbol may retrieve word variants: ((doc sach) or (toc sach)) dao hang xa hoi. hieu ((va chat) OR (van chat)) xuc van danh di cua tre*.
