Perhaps you should try some spelling variations:
"coder segmentation based _ programming" » "color segmentation based _ programming" (Expand search), "over segmentation based _ programming" (Expand search), "gender segmentation based _ programming" (Expand search), "coder segmentation and _ programming" (Expand search)
"python xcode java python programming" » "python code java python programming" (Expand search), "python cuda java python programming" (Expand search), "python codes java python programming" (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: "((\"coder segmentation based _ programming\") OR (\"python xcode java python programming\"))~".
• Removing quotes may allow a broader search: (( coder segmentation based _ programming ) OR ( python xcode java python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("coder segmentation based _ programming") OR ("python xcode java python programming"))*.
