Talvez debería tentar con algunhas variantes ortográficas:
integration functions » integration functional, integrating functions, interactions functions
programming recursion » programming decision, programming session, programming decisions
programming defining » programming designing, programming learning, programming reasoning
basic struts » basic truth, basic strokes, basic study

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: integration functions ((programming defining) OR (programming recursion)) basic struts~.
• Adding a wildcard symbol may retrieve word variants: integration functions ((programming defining) or (programming recursion)) basic struts*.
