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