Perhaps you should try some spelling variations:
decrease complex » disease complex (Expand search), decreased compared (Expand search), protease complex (Expand search)
complex process » complexo processo (Expand search), complex projects (Expand search), complex problems (Expand search)
based sectors » based vectors (Expand search), based sensors (Expand search), based vector (Expand search)
python based » action based (Expand search)
decrease of » decrease in (Expand search)
of decrease » or decrease (Expand search), not decrease (Expand search), to decrease (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 of decrease complex process ) OR ( python based sectors python programming ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease of decrease complex process ) OR ( python based sectors python programming ))*.
