• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (thu sach)) y nang x hoi. hieu van chat cuc ban ((anh de) OR (hanh de)) cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) OR (thu sach)) y nang x hoi. hieu van chat cuc ban ((anh de) or (hanh de)) cua tre~".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) OR (thu sach)) y nang x hoi. hieu van chat cuc ban ((anh de) or (hanh de)) cua tre*.
