• If you are trying to use Boolean operators, they must be ALL CAPS: (( te sach tai hoc sach nham thu thang ) OR ( tu sach bai doc ((anh ho) OR (anh hoc)) thu thong ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( te sach tai hoc sach nham thu thang ) or ( tu sach bai doc ((anh ho) OR (anh hoc)) thu thong ))~".
• Adding a wildcard symbol may retrieve word variants: (( te sach tai hoc sach nham thu thang ) or ( tu sach bai doc ((anh ho) OR (anh hoc)) thu thong ))*.
