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