Perhaps you should try some spelling variations:
green's functions » green's function
australian energy » australian early, australian federal, australian army
11th australian » 17th australian, 10th australian, 12th australian
energy fraction » energy traction, energy function, energy action
green functions » green's function
10 australian » _ australian, 2 australian, 3 australian

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: (( 11th australian energy fraction ) OR ( 10 australian ((green functions) OR (green's functions)) ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( 11th australian energy fraction ) or ( 10 australian ((green functions) OR (green's functions)) ))*".
