Perhaps you should try some spelling variations:
"advanced applications _ python programming" » "and applications _ python programming" (Expand search), "advanced glycation _ python programming" (Expand search), "based applications _ python programming" (Expand search)
"and convolutional and clean program" » "and conventional and clean program" (Expand search), "of convolutional and clean program" (Expand search), "_ convolutional and clean program" (Expand search), "and convolution and clean program" (Expand search), "and convolutional codes clean program" (Expand search), "and convolutional and learn program" (Expand search), "and convolutional and loan program" (Expand search), "and convolutional and bean program" (Expand search)

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"and convolutional and clean program\") OR (\"advanced applications _ python programming\"))~".
• Removing quotes may allow a broader search: (( and convolutional and clean program ) OR ( advanced applications _ python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("and convolutional and clean program") OR ("advanced applications _ python programming"))*.
