• Performing a fuzzy search may retrieve terms with similar spellings: su sach ky dang xa hoi. ((hieu ve) OR (hieu van)) ((cam xuc) or (pham cuc)) ban hanh vai cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ky dang xa hoi. ((hieu ve) OR (hieu van)) ((cam xuc) OR (pham cuc)) ban hanh vai cuu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ky dang xa hoi. ((hieu ve) OR (hieu van)) ((cam xuc) or (pham cuc)) ban hanh vai cuu tre*".
