• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"te sach minh bi gia tuong\") or (((((\"tu sach kinh ai gia cong\") or (\"tu sach kinh bbai giaing cong\"))) or (((\"tu sach kinh hai gia cong\") OR (\"tu cach kinh hai gia cong\"))))))".
• Removing quotes may allow a broader search: (( te sach minh bi gia tuong ) or ((((( tu sach kinh ai gia cong ) or ( tu sach kinh bbai giaing cong ))) or ((( tu sach kinh hai gia cong ) OR ( tu cach kinh hai gia cong )))))).
• Adding a wildcard symbol may retrieve word variants: (("te sach minh bi gia tuong") or ((((("tu sach kinh ai gia cong") or ("tu sach kinh bbai giaing cong"))) or ((("tu sach kinh hai gia cong") OR ("tu cach kinh hai gia cong"))))))*.
