• Performing a fuzzy search may retrieve terms with similar spellings: vu sach ty ((nang co) OR (nang cao)) loi. hieu ((ve cam) or (ve cac)) xuc va thanh lai cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu sach ty ((nang co) OR (nang cao)) loi. hieu ((ve cam) OR (ve cac)) xuc va thanh lai cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sach ty ((nang co) OR (nang cao)) loi. hieu ((ve cam) or (ve cac)) xuc va thanh lai cua te".
• Adding a wildcard symbol may retrieve word variants: vu sach ty ((nang co) OR (nang cao)) loi. hieu ((ve cam) or (ve cac)) xuc va thanh lai cua te*.
