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