• Performing a fuzzy search may retrieve terms with similar spellings: thu sach ty dang xa hoi. hieu ve cam luc va dinh vai ((cuu tre) or (((cau treo) OR (cau theo))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ty dang xa hoi. hieu ve cam luc va dinh vai ((cuu tre) OR (((cau treo) OR (cau theo)))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ty dang xa hoi. hieu ve cam luc va dinh vai ((cuu tre) or (((cau treo) OR (cau theo))))".
• Adding a wildcard symbol may retrieve word variants: thu sach ty dang xa hoi. hieu ve cam luc va dinh vai ((cuu tre) or (((cau treo) OR (cau theo))))*.
