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