Perhaps you should try some spelling variations:
technical paper » technical papers
mali technical » ii technical, iii technical, i technical
world actions » world auctions, world fictions, world nations
api technical » ii technical, iii technical, i technical
world action » world auctions, world section, world fiction

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