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