• Performing a fuzzy search may retrieve terms with similar spellings: (( ((te sach) or (toc sach)) kinh ((do gia) OR (do giua)) dung ) or ((( tu san trinh ((do gia) OR (do giua))m muong ) or ((((( tu sac trinh ho gia tuong ) or ( tu sac trinh ho gia dong ))) or ( tu cac trinh ((do gia) OR (do giua))n muong ))))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( ((te sach) OR (toc sach)) kinh ((do gia) OR (do giua)) dung ) OR ((( tu san trinh ((do gia) OR (do giua))m muong ) OR ((((( tu sac trinh ho gia tuong ) OR ( tu sac trinh ho gia dong ))) OR ( tu cac trinh ((do gia) OR (do giua))n muong ))))))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( ((te sach) or (toc sach)) kinh ((do gia) OR (do giua)) dung ) or ((( tu san trinh ((do gia) OR (do giua))m muong ) or ((((( tu sac trinh ho gia tuong ) or ( tu sac trinh ho gia dong ))) or ( tu cac trinh ((do gia) OR (do giua))n muong ))))))*".
