• If you are trying to use Boolean operators, they must be ALL CAPS: (("thu sach kinh te gia cong") OR ((((("thu sach minh te gia cong") OR ("thu sac tinh te gia cong"))) OR ("thu cach kinh te va cong")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"thu sach kinh te gia cong\") or (((((\"thu sach minh te gia cong\") OR (\"thu sac tinh te gia cong\"))) or (\"thu cach kinh te va cong\"))))".
• Removing quotes may allow a broader search: (( thu sach kinh te gia cong ) or ((((( thu sach minh te gia cong ) OR ( thu sac tinh te gia cong ))) or ( thu cach kinh te va cong )))).
• Adding a wildcard symbol may retrieve word variants: (("thu sach kinh te gia cong") or ((((("thu sach minh te gia cong") OR ("thu sac tinh te gia cong"))) or ("thu cach kinh te va cong"))))*.
