• Performing a fuzzy search may retrieve terms with similar spellings: hoc thien tinh - ((((hanh trinh) OR (hanh chinh))) or (canh tranh)) cua cuong cong nhanh thang cac~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc thien tinh - ((((hanh trinh) OR (hanh chinh))) OR (canh tranh)) cua cuong cong nhanh thang cac.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thien tinh - ((((hanh trinh) OR (hanh chinh))) or (canh tranh)) cua cuong cong nhanh thang cac".
• Adding a wildcard symbol may retrieve word variants: hoc thien tinh - ((((hanh trinh) OR (hanh chinh))) or (canh tranh)) cua cuong cong nhanh thang cac*.
