• Performing a fuzzy search may retrieve terms with similar spellings: su sach ky nang xa hoi. dieu ((hien cac) OR (vien cac)) bo va ((hanh lai) or (hanh lam)) cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ky nang xa hoi. dieu ((hien cac) OR (vien cac)) bo va ((hanh lai) OR (hanh lam)) cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ky nang xa hoi. dieu ((hien cac) OR (vien cac)) bo va ((hanh lai) or (hanh lam)) cua te".
• Adding a wildcard symbol may retrieve word variants: su sach ky nang xa hoi. dieu ((hien cac) OR (vien cac)) bo va ((hanh lai) or (hanh lam)) cua te*.
