Perhaps you should try some spelling variations:
functions technical » function technique, solutions technical, indications technical
apis technical » apps technical, basics technical
api technical » mali technical, i technical, 2 technical
iii technical » 2 technical
ii technical » 2 technical

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: (( world ((apis technical) OR (functions technical)) paper ) OR ( world ((((api technical) OR (iii technical))) OR (ii technical)) paper )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( world ((apis technical) or (functions technical)) paper ) or ( world ((((api technical) OR (iii technical))) or (ii technical)) paper ))".
• Adding a wildcard symbol may retrieve word variants: (( world ((apis technical) or (functions technical)) paper ) or ( world ((((api technical) OR (iii technical))) or (ii technical)) paper ))*.
