Perhaps you should try some spelling variations:
decrease processes » disease processes (Expand search), decay processes (Expand search)
decrease decrease » decrease release (Expand search), disease decreases (Expand search), decrease sucrose (Expand search)
chemical process » chemical processes (Expand search), chemical profile (Expand search)
active chemical » activity chemical (Expand search), active medical (Expand search), activities chemical (Expand search)
script active » script act (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: "(( decrease NOT decrease decrease processes ) OR ( python script active chemical process ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease NOT decrease decrease processes ) OR ( python script active chemical process ))*.
