- The words AND, OR and NOT may confuse the search; try adding quotes: "\"((khoa hoc) or (hoa hoc)) & ((kham OR khai) or nhan) (((pha\" or phap\") or phan\") or pham\")~".
- Removing quotes may allow a broader search: ((khoa hoc) or (hoa hoc)) & ((kham OR khai) or nhan) (((pha or phap ) or phan ) or pham )~.
- Adding a wildcard symbol may retrieve word variants: "((khoa hoc) or (hoa hoc)) & ((kham OR khai) or nhan) (((pha" or phap") or phan") or pham")*.
