Perhaps you should try some spelling variations:
deployment testing » deployment using, deployment deploying
deployment adding » deployment using, deployment planning, deployment getting
oecd economies » oecd economic

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: oecd economies ((deployment adding) OR (deployment testing)) paper.
• Adding a wildcard symbol may retrieve word variants: oecd economies ((deployment adding) or (deployment testing)) paper*.
