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