• If you are trying to use Boolean operators, they must be ALL CAPS: (((( ear originsal reference ) OR ( ear origins reference ))) OR ((((( ear horizons references ) OR ( far horizons references ))) OR ((((( year kriging referencess ) OR ( early origins references ))) OR ( year proteins references )))))).
• Adding a wildcard symbol may retrieve word variants: (((( ear originsal reference ) or ( ear origins reference ))) or ((((( ear horizons references ) or ( far horizons references ))) or ((((( year kriging referencess ) or ( early origins references ))) or ( year proteins references ))))))*.
