• Performing a fuzzy search may retrieve terms with similar spellings: te ((sach va) OR (sach dao)) nang xa hoi. thi hanh cham loc va danh ((dien cu) or (dien cua)) triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach va) OR (sach dao)) nang xa hoi. thi hanh cham loc va danh ((dien cu) OR (dien cua)) triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach va) OR (sach dao)) nang xa hoi. thi hanh cham loc va danh ((dien cu) or (dien cua)) triet".
• Adding a wildcard symbol may retrieve word variants: te ((sach va) OR (sach dao)) nang xa hoi. thi hanh cham loc va danh ((dien cu) or (dien cua)) triet*.
