Perhaps you should try some spelling variations:
phase processes » peace processes (Expand search), these processes (Expand search), plate processes (Expand search)
decrease tooth » decrease with (Expand search), decrease food (Expand search), decrease costs (Expand search)
tooth disease » mouth disease (Expand search)
disease phase » disease pain (Expand search), disease pad (Expand search), disease part (Expand search)
python redes » python regius (Expand search), python code (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 tooth disease phase processes ) OR ( python redes p2p python programming ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease tooth disease phase processes ) OR ( python redes p2p python programming ))*.
