Perhaps you should try some spelling variations:
khong minh » thong minh, duong minh, trong minh
sach thue » sach thu, sach thieu, sach tham
nguoi cor » nguoi co, nguoi cong, nguoi moi
hong minh » thong minh, hong hinh, song minh
sach cha » sach nha, sach che, sach ha
me nguoi » ma nguoi, le nguoi, ke nguoi

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: thu ((sach cha) or (sach thue)) me nguoi cor ((hong minh) or (((khong minh) OR (hoang minh))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu ((sach cha) OR (sach thue)) me nguoi cor ((hong minh) OR (((khong minh) OR (hoang minh)))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu ((sach cha) or (sach thue)) me nguoi cor ((hong minh) or (((khong minh) OR (hoang minh))))".
• Adding a wildcard symbol may retrieve word variants: thu ((sach cha) or (sach thue)) me nguoi cor ((hong minh) or (((khong minh) OR (hoang minh))))*.
