• Performing a fuzzy search may retrieve terms with similar spellings: thu sach ky ((((lang xa) OR (dang xay))) or (dang van)) hoi. hieu van dau phuc va danh dai cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ky ((((lang xa) OR (dang xay))) OR (dang van)) hoi. hieu van dau phuc va danh dai cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ky ((((lang xa) OR (dang xay))) or (dang van)) hoi. hieu van dau phuc va danh dai cuu tre".
• Adding a wildcard symbol may retrieve word variants: thu sach ky ((((lang xa) OR (dang xay))) or (dang van)) hoi. hieu van dau phuc va danh dai cuu tre*.
