Perhaps you should try some spelling variations:
"ear originsal reference" » "ear original references", "ear origins references", "ear regional reference", "ear origins reference", "her original reference", "year origins reference"
"ear proteins references" » "ear process references", "ear properties references", "ear prospects references", "tear proteins references", "par proteins references", "early proteins references"
"year resins references" » "year lesions references", "year designs references", "year results references", "year begins references", "year response references"
"heart brain references" » "heart beating references"
"ear brain references" » "car brain references", "early brain references", "mr brain references"

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (((("ear originsal reference") OR ((("ear brain references") OR ("heart brain references"))))) OR ((("ear proteins references") OR ("year resins references")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"ear originsal reference\") or (((\"ear brain references\") OR (\"heart brain references\"))))) or (((\"ear proteins references\") or (\"year resins references\"))))".
• Removing quotes may allow a broader search: (((( ear originsal reference ) or ((( ear brain references ) OR ( heart brain references ))))) or ((( ear proteins references ) or ( year resins references )))).
• Adding a wildcard symbol may retrieve word variants: (((("ear originsal reference") or ((("ear brain references") OR ("heart brain references"))))) or ((("ear proteins references") or ("year resins references"))))*.
