decrease and » decreases and (Expand search), decrease in (Expand search), decrease of (Expand search)
and diseases » and disease (Expand search)
python regis » python regius (Expand search), python redes (Expand search)

• If you are trying to use Boolean operators, they must be ALL CAPS: (( decrease AND diseases based processes ) OR ( python regis pitons python programming ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease and diseases based processes ) OR ( python regis pitons python programming ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease and diseases based processes ) OR ( python regis pitons python programming ))*.
