• If you are trying to use Boolean operators, they must be ALL CAPS: (((( tu sach minh va gia cong ) OR ((((((( tu sac tinh do gia tuong ) OR ( tu dac tinh do gia tuong ))) OR ( tu sach kinh ((do va) OR (so va)) tuong ))) OR ( tu bac tinh do gia cuong ))))) OR ((( tu may trinh do giam muong ) OR ( tu ma trinh do giam muong ))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((( tu sach minh va gia cong ) or ((((((( tu sac tinh do gia tuong ) or ( tu dac tinh do gia tuong ))) or ( tu sach kinh ((do va) OR (so va)) tuong ))) or ( tu bac tinh do gia cuong ))))) or ((( tu may trinh do giam muong ) or ( tu ma trinh do giam muong ))))~".
• Adding a wildcard symbol may retrieve word variants: (((( tu sach minh va gia cong ) or ((((((( tu sac tinh do gia tuong ) or ( tu dac tinh do gia tuong ))) or ( tu sach kinh ((do va) OR (so va)) tuong ))) or ( tu bac tinh do gia cuong ))))) or ((( tu may trinh do giam muong ) or ( tu ma trinh do giam muong ))))*.
