• Performing a fuzzy search may retrieve terms with similar spellings: te ((((sach vay) OR (sach nay))) or (sach 2)) nang xa hoi. hieu ve cham duoc va danh doi cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te ((((sach vay) OR (sach nay))) OR (sach 2)) nang xa hoi. hieu ve cham duoc va danh doi cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((((sach vay) OR (sach nay))) or (sach 2)) nang xa hoi. hieu ve cham duoc va danh doi cua triet*".
