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