Perhaps you should try some spelling variations:
mali technical » iii technical, i technical
api technical » iii technical, i technical, 2 technical
ii technical » 2 technical, 7 technical
world apis » world apps, world anis, world kpis

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