Perhaps you should try some spelling variations:
decreases disease » diseases disease (Expand search), decreases adipose (Expand search), decreases breast (Expand search)
disease processes » disease process (Expand search), disease progress (Expand search), these processes (Expand search)
surface python » surface method (Expand search), surface path (Expand search), surface phonon (Expand search)
track surface » crack surface (Expand search), back surface (Expand search), tank surface (Expand search)
python track » python task (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 _ decreases disease processes ) OR ( python track surface python programming ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease _ decreases disease processes ) OR ( python track surface python programming ))*.
