Perhaps you should try some spelling variations:
"advanced composite in python programming" » "advanced composites in python programming" (Expand search), "advanced composite and python programming" (Expand search), "advanced composite _ python programming" (Expand search)
"and convolutional bar coding program" » "and conventional bar coding program" (Expand search), "of convolutional bar coding program" (Expand search), "_ convolutional bar coding program" (Expand search), "and convolutional bag coding program" (Expand search), "and convolutional and coding program" (Expand search), "and convolutional net coding program" (Expand search), "and convolutional bar cloning program" (Expand search), "and convolutional bar loading program" (Expand search), "and convolutional bar cooling programs" (Expand search), "and convolutional b coding program" (Expand search), "and convolutional lrr coding program" (Expand search), "and convolutional map coding 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 bar coding program\") OR (\"advanced composite in python programming\"))~".
• Removing quotes may allow a broader search: (( and convolutional bar coding program ) OR ( advanced composite in python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("and convolutional bar coding program") OR ("advanced composite in python programming"))*.
