• If you are trying to use Boolean operators, they must be ALL CAPS: ((geotechnical engineering) OR (biomedical engineering)) & applied ((earth science) OR (health sciences)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((geotechnical engineering) or (biomedical engineering)) & applied ((earth science) OR (health sciences))".
• Adding a wildcard symbol may retrieve word variants: ((geotechnical engineering) or (biomedical engineering)) & applied ((earth science) OR (health sciences))*.
