removal decrease » neuronal decrease (Expand search), removal case (Expand search)
decrease and » decreases and (Expand search), decrease in (Expand search), decrease of (Expand search)
piton python » pitons python (Expand search), in python (Expand search), with python (Expand search)

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