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