Talvez debería tentar con algunhas variantes ortográficas:
interaction conditions » integration conditions, interactions conditional, extraction conditions
programming recursion » programming decision, programming session, programming decisions
programming learning » programmed learning, programming using, programming building
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: interaction conditions ((programming learning) OR (programming recursion)) basic struts~.
• Adding a wildcard symbol may retrieve word variants: interaction conditions ((programming learning) or (programming recursion)) basic struts*.
