Perhaps you should try some spelling variations:
"experimental facility" » "experimental facilities"
"experimental facts" » "experimental aspects", "experimental facilities"
"experimental film" » "experimental films", "experimental field"

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