Perhaps you should try some spelling variations:
"lung module example" » "lung modules example", "lung modules examples", "lung model example", "lung nodules example", "lunar module example", "lung modeler example"
"lungs nodule example" » "lungs modules example", "lungs node example", "lungs noble example", "lung nodules example"
"lung nodule eagle" » "lung double eagle", "lung nodule case", "lung nodule false"

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: (("lung nodule eagle") OR ((("lung module example") OR ("lungs nodule example")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"lung nodule eagle\") or (((\"lung module example\") OR (\"lungs nodule example\"))))".
• Removing quotes may allow a broader search: (( lung nodule eagle ) or ((( lung module example ) OR ( lungs nodule example )))).
• Adding a wildcard symbol may retrieve word variants: (("lung nodule eagle") or ((("lung module example") OR ("lungs nodule example"))))*.
