Perhaps you should try some spelling variations:
"_ convolutional coding coding program" » "_ convolutional codes coding program" (Expand search), "_ convolutional code coding program" (Expand search), "_ convolutional long coding program" (Expand search), "_ convolutional coding cloning program" (Expand search), "_ convolutional coding loading program" (Expand search), "_ convolutional coding cooling programs" (Expand search), "_ convolutional coding decoding program" (Expand search), "_ convolutional coding using program" (Expand search), "_ convolutional coding canine program" (Expand search)
"advanced text and python programming" » "advanced textile and python programming" (Expand search), "advanced cell and python programming" (Expand search), "advanced tool and python programming" (Expand search), "advanced text in python programming" (Expand search), "advanced text on python programming" (Expand search), "advanced text api 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: "((\"_ convolutional coding coding program\") OR (\"advanced text and python programming\"))~".
• Removing quotes may allow a broader search: (( _ convolutional coding coding program ) OR ( advanced text and python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("_ convolutional coding coding program") OR ("advanced text and python programming"))*.
