Perhaps you should try some spelling variations:
"surface functionalities in python programming" » "surface functionalized in python programming" (Expand search), "surface functionality in python programming" (Expand search), "surface functionalization in python programming" (Expand search), "surface functionalities of python programming" (Expand search), "surface functionals in python programming" (Expand search), "surface functionalities _ python programming" (Expand search)
"based convolution and coding program" » "based convolutional and coding program" (Expand search), "and convolution and coding program" (Expand search), "based evolution and coding program" (Expand search), "based revolution and coding program" (Expand search), "based convention and coding program" (Expand search), "based convolution and cloning program" (Expand search), "based convolution and loading program" (Expand search), "based convolution and cooling programs" (Expand search), "based convolution and coping program" (Expand search), "based convolution and cooling program" (Expand search), "based convolution and cooking 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: "((\"based convolution and coding program\") OR (\"surface functionalities in python programming\"))~".
• Removing quotes may allow a broader search: (( based convolution and coding program ) OR ( surface functionalities in python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("based convolution and coding program") OR ("surface functionalities in python programming"))*.
