• If you are trying to use Boolean operators, they must be ALL CAPS: (((("tu sach minh de giau cuong") OR ((("tu sach minh do gia tuong") OR ("tu sach minh do gia cuong"))))) OR ("tu may tinh doi giam muong")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"tu sach minh de giau cuong\") or (((\"tu sach minh do gia tuong\") OR (\"tu sach minh do gia cuong\"))))) or (\"tu may tinh doi giam muong\"))".
• Removing quotes may allow a broader search: (((( tu sach minh de giau cuong ) or ((( tu sach minh do gia tuong ) OR ( tu sach minh do gia cuong ))))) or ( tu may tinh doi giam muong )).
• Adding a wildcard symbol may retrieve word variants: (((("tu sach minh de giau cuong") or ((("tu sach minh do gia tuong") OR ("tu sach minh do gia cuong"))))) or ("tu may tinh doi giam muong"))*.
