• Performing a fuzzy search may retrieve terms with similar spellings: so ((nganh ky) OR (nganh xay)) lang van hoi. hieu vien cac duc va ((hanh hai) or (nhanh ha)) cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: so ((nganh ky) OR (nganh xay)) lang van hoi. hieu vien cac duc va ((hanh hai) OR (nhanh ha)) cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so ((nganh ky) OR (nganh xay)) lang van hoi. hieu vien cac duc va ((hanh hai) or (nhanh ha)) cua te".
• Adding a wildcard symbol may retrieve word variants: so ((nganh ky) OR (nganh xay)) lang van hoi. hieu vien cac duc va ((hanh hai) or (nhanh ha)) cua te*.
