Perhaps you should try some spelling variations:
"when resources software" » "when outsourced software", "when measures software", "open resources software", "ocean resources software", "own resources software"
"ocean resource software" » "ocean opensource software", "ocean resonance software", "ocean reduce software", "ocean resources software", "human resource software"
"ocean source software" » "ocean sources software", "ocean resources software", "ocean surface software"

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: (("when resources software") OR ((("ocean resource software") OR ("ocean source software")))).
• Removing quotes may allow a broader search: (( when resources software ) or ((( ocean resource software ) or ( ocean source software )))).
• Adding a wildcard symbol may retrieve word variants: (("when resources software") or ((("ocean resource software") or ("ocean source software"))))*.
