• If you are trying to use Boolean operators, they must be ALL CAPS: (("ear original references") OR ((("ear origin references") OR ((("year origins references") OR ("year proteins references")))))).
• Removing quotes may allow a broader search: (( ear original references ) or ((( ear origin references ) or ((( year origins references ) or ( year proteins references )))))).
• Adding a wildcard symbol may retrieve word variants: (("ear original references") or ((("ear origin references") or ((("year origins references") or ("year proteins references"))))))*.
