Perhaps you should try some spelling variations:
"_ convolutional and feeding program" » "_ convolution and feeding program" (Expand search), "_ conventional and feeding program" (Expand search), "_ convolutional codes feeding program" (Expand search)
"advanced oxidation in python programming" » "advanced oxidation and python programming" (Expand search), "advanced oxidation of python programming" (Expand search), "advanced oxidation _ python programming" (Expand search)

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("_ convolutional and feeding program") OR ("advanced oxidation in python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"_ convolutional and feeding program\") OR (\"advanced oxidation in python programming\"))".
• Removing quotes may allow a broader search: (( _ convolutional and feeding program ) OR ( advanced oxidation in python programming )).
• Adding a wildcard symbol may retrieve word variants: (("_ convolutional and feeding program") OR ("advanced oxidation in python programming"))*.
