• If you are trying to use Boolean operators, they must be ALL CAPS: (((( te sach ((dang de) OR (dang do)) gian muong ) OR ((( thu sach tranh de giain muong ) OR ((( su sach han de giaun muong ) OR ( su sach han de giai muong ))))))) OR ((( tu sac trinh ky gia cong ) OR ( tu cac trinh do gia cong ))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((( te sach ((dang de) OR (dang do)) gian muong ) or ((( thu sach tranh de giain muong ) or ((( su sach han de giaun muong ) or ( su sach han de giai muong ))))))) or ((( tu sac trinh ky gia cong ) or ( tu cac trinh do gia cong ))))~".
• Adding a wildcard symbol may retrieve word variants: (((( te sach ((dang de) OR (dang do)) gian muong ) or ((( thu sach tranh de giain muong ) or ((( su sach han de giaun muong ) or ( su sach han de giai muong ))))))) or ((( tu sac trinh ky gia cong ) or ( tu cac trinh do gia cong ))))*.
