If you are trying to use Boolean operators, they must be ALL CAPS: "((\"khoa hoc & pham phap\") OR (\"khoa hoc & pham (nhat\" OR nhan\")))".
The words AND, OR and NOT may confuse the search; try adding quotes: "\"((\\"khoa hoc & pham phap\\") or (\\"khoa hoc & pham (nhat\\" OR nhan\\")))\"".
Removing quotes may allow a broader search: (( khoa hoc & pham phap ) or ( khoa hoc & pham (nhat OR nhan ))).
