Perhaps you should try some spelling variations:
"ecologie / methodological" » "ecologies / methodological", "ecologic / methodological", "ecologist / methodological"
"oncologic / methodologies" » "oncology / methodologies", "oncologic / methodology"

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: (("ecologie / methodological") OR ("oncologic / methodologies"))*.
• Removing quotes may allow a broader search: (( ecologie / methodological ) or ( oncologic / methodologies ))*.
