Perhaps you should try some spelling variations:
"experimental fields" » "experimental field", "experimental films", "experimental fires"
"experimental yield" » "experimental field", "experiments field", "experimental time"
"experimental film" » "experimental films", "experimental field", "experimental facts"

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: (((("experimental film") OR ("experimental fluid"))) OR ((("experimental fields") OR ("experimental yield")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"experimental film\") OR (\"experimental fluid\"))) or (((\"experimental fields\") or (\"experimental yield\"))))".
• Removing quotes may allow a broader search: (((( experimental film ) OR ( experimental fluid ))) or ((( experimental fields ) or ( experimental yield )))).
• Adding a wildcard symbol may retrieve word variants: (((("experimental film") OR ("experimental fluid"))) or ((("experimental fields") or ("experimental yield"))))*.
