Perhaps you should try some spelling variations:
disease controlled » disease:a controlled (Expand search), disease controlling (Expand search), disease control (Expand search)
controlled process » control process (Expand search), controlled access (Expand search), controlled pore (Expand search)
decrease and » decreases and (Expand search), decrease in (Expand search), decrease of (Expand search)
python code » python coding (Expand search), python redes (Expand search)
in python » _ python (Expand search)
code in » code and (Expand search)

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (( decrease AND disease controlled process ) OR ( python code in python programming ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease and disease controlled process ) OR ( python code in python programming ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease and disease controlled process ) OR ( python code in python programming ))*.
