Perhaps you should try some spelling variations:
disease increase » disease increased (Expand search), disease increases (Expand search), disease decreases (Expand search)
increase process » increase access (Expand search), increase protein (Expand search), increase project (Expand search)
decrease spot » decrease sod (Expand search), decrease soon (Expand search), decrease of (Expand search)
spot disease » host disease (Expand search), wilt disease (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 spot disease increase process ) OR ( python redes p2p python programming ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease spot disease increase process ) OR ( python redes p2p python programming ))*.
