Perhaps you should try some spelling variations:
resource software » resources software, source software, opensource software
when resources » open resources, ocean resources, own resources
ocean resource » ocean resources, human resource
open resource » open resources, open source, open sources

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "\"((\\"((open resource) OR (when resources)) software\\") or (\\"ocean resource software\\"))\"".
• Removing quotes may allow a broader search: (( ((open resource) OR (when resources)) software ) or ( ocean resource software )).
