Perhaps you should try some spelling variations:
"botanical based" » "botanical names", "botanicals used", "botanical garden"
"botanical name" » "botanical names", "botanical notes", "botanical dance"
"botanical bird" » "botanical world", "botanical first", "botanical work"

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