• Performing a fuzzy search may retrieve terms with similar spellings: toc sach tru ((lang xa) or (dang xay)) hoi. hieu ((qua cao) OR (qua cai)) suc va danh vai cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: toc sach tru ((lang xa) OR (dang xay)) hoi. hieu ((qua cao) OR (qua cai)) suc va danh vai cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc sach tru ((lang xa) or (dang xay)) hoi. hieu ((qua cao) OR (qua cai)) suc va danh vai cua te*".
