"her kriging references" » "her origins references", "her driving references", "her pricing references", "her bringing references", "when kriging references", "her origin references"
"early motions references" » "early motion references", "early options references", "early actions references", "early abortions references", "early emotional references"
"year origin references" » "year brain references", "year origins references", "years origins references", "yeast origin 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: (("her kriging references") OR ((((("early horizons references") OR ("early motions references"))) OR ("year origin references")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"her kriging references\") or (((((\"early horizons references\") OR (\"early motions references\"))) or (\"year origin references\"))))".
• Removing quotes may allow a broader search: (( her kriging references ) or ((((( early horizons references ) OR ( early motions references ))) or ( year origin references )))).
• Adding a wildcard symbol may retrieve word variants: (("her kriging references") or ((((("early horizons references") OR ("early motions references"))) or ("year origin references"))))*.
