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

Try widening your search to All Fields.

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 ((("ecologic / methodologies") OR ("oncologic / methodologies")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"ecologie / methodological\") or (((\"ecologic / methodologies\") OR (\"oncologic / methodologies\"))))".
• Removing quotes may allow a broader search: (( ecologie / methodological ) or ((( ecologic / methodologies ) OR ( oncologic / methodologies )))).
• Adding a wildcard symbol may retrieve word variants: (("ecologie / methodological") or ((("ecologic / methodologies") OR ("oncologic / methodologies"))))*.
