• Performing a fuzzy search may retrieve terms with similar spellings: ((((thu sach) OR (thuat sach))) or (te sach)) ky nang xa hoi. hieu su cham xuc va hanh dai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((((thu sach) OR (thuat sach))) OR (te sach)) ky nang xa hoi. hieu su cham xuc va hanh dai cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((thu sach) OR (thuat sach))) or (te sach)) ky nang xa hoi. hieu su cham xuc va hanh dai cua tre".
• Adding a wildcard symbol may retrieve word variants: ((((thu sach) OR (thuat sach))) or (te sach)) ky nang xa hoi. hieu su cham xuc va hanh dai cua tre*.
