• Performing a fuzzy search may retrieve terms with similar spellings: tu ((((sach hay) OR (sach vay))) or (sach nay)) dang van hoi. lieu va cac duc va nang tai cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((((sach hay) OR (sach vay))) OR (sach nay)) dang van hoi. lieu va cac duc va nang tai cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((((sach hay) OR (sach vay))) or (sach nay)) dang van hoi. lieu va cac duc va nang tai cua te*".
