Try widening your search to All Fields.

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (((("computer apple. in life science") OR ("computer apple. in life sciences"))) OR ((("computer example. in fire science") OR ("computers applied. in firm science")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"computer apple. in life science\") OR (\"computer apple. in life sciences\"))) or (((\"computer example. in fire science\") or (\"computers applied. in firm science\"))))".
• Removing quotes may allow a broader search: (((( computer apple. in life science ) OR ( computer apple. in life sciences ))) or ((( computer example. in fire science ) or ( computers applied. in firm science )))).
• Adding a wildcard symbol may retrieve word variants: (((("computer apple. in life science") OR ("computer apple. in life sciences"))) or ((("computer example. in fire science") or ("computers applied. in firm science"))))*.
