Perhaps you should try some spelling variations:
"bone narrow transplantation" » "bone marrow transplantations", "bone eyebrow transplantation", "bone national transplantation", "done narrow transplantation", "one narrow transplantation", "ions narrow transplantation"
"fine narrow transplantation" » "fine marrow transplantations", "fine eyebrow transplantation", "fine national transplantation", "lines narrow transplantation", "done narrow transplantation", "one narrow transplantation"

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: (("bone marrow transplantation") OR ((("bone narrow transplantation") OR ("fine narrow transplantation")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"bone marrow transplantation\") or (((\"bone narrow transplantation\") OR (\"fine narrow transplantation\"))))".
• Removing quotes may allow a broader search: (( bone marrow transplantation ) or ((( bone narrow transplantation ) OR ( fine narrow transplantation )))).
• Adding a wildcard symbol may retrieve word variants: (("bone marrow transplantation") or ((("bone narrow transplantation") OR ("fine narrow transplantation"))))*.
