Perhaps you should try some spelling variations:
reflection program » selection program (Expand search), collection program (Expand search), detection program (Expand search)
decrease processes » disease processes (Expand search), decay processes (Expand search)
decrease decrease » decrease release (Expand search), disease decreases (Expand search), decrease sucrose (Expand search)
photon reflection » photon detection (Expand search), photo selection (Expand search), person reflections (Expand search)
script photon » script python (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 _ decrease decrease processes ) OR ( python script photon reflection program ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease _ decrease decrease processes ) OR ( python script photon reflection program ))*.
