Perhaps you should try some spelling variations:
"experimental music" » "experimental murine", "experimental mouse", "experimental mass"
"experimental basic" » "experimental basis", "experimental brain", "experimental physics"
"experimental bases" » "experimental basis", "experimental case", "experimental analyses"

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