• Performing a fuzzy search may retrieve terms with similar spellings: thu ((sach ky) OR (sach y)) nang xa hoi. ((hieu ve) or (hieu van)) cam cuc ban hang tai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu ((sach ky) OR (sach y)) nang xa hoi. ((hieu ve) OR (hieu van)) cam cuc ban hang tai cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu ((sach ky) OR (sach y)) nang xa hoi. ((hieu ve) or (hieu van)) cam cuc ban hang tai cua tre".
• Adding a wildcard symbol may retrieve word variants: thu ((sach ky) OR (sach y)) nang xa hoi. ((hieu ve) or (hieu van)) cam cuc ban hang tai cua tre*.
