Perhaps you should try some spelling variations:
response complexity » response complex (Expand search), discourse complexity (Expand search), relations complexity (Expand search)
costing methods » costing method (Expand search)
poder response » power response (Expand search), poorer response (Expand search), poor response (Expand search)
methods python » methods action (Expand search), pythons python (Expand search), methods method (Expand search)
using costing » using coating (Expand search), using boosting (Expand search), using coatings (Expand search)

You may be able to get more results by adjusting your search query.

• Removing quotes may allow a broader search: (( poder response complexity control program ) OR ( using costing methods python programming ))~.
