Perhaps you should try some spelling variations:
implementing control » implement control (Expand search), imprinting control (Expand search), implementing cost (Expand search)
and implementing » of implementing (Expand search), _ implementing (Expand search), and implementation (Expand search)
python python » pythons python (Expand search), piton python (Expand search), pitons python (Expand search)
using python » usando python (Expand search), in python (Expand search)
using using » housing using (Expand search), aging using (Expand search), ring using (Expand search)
model and » modeling and (Expand search)

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: (( model AND implementing control program ) OR ( using using python python programming ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( model and implementing control program ) OR ( using using python python programming ))~".
• Adding a wildcard symbol may retrieve word variants: (( model and implementing control program ) OR ( using using python python programming ))*.
