Perhaps you should try some spelling variations:
lipid environment » grid environment, arid environment, wind environment
world environment » work environment, grid environment, arid environment
oecd environment » oecd environmental, field environment, covid environment
working papers » working paper

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: ((oecd environment) OR (((world environment) OR (lipid environment)))) working papers.
• Adding a wildcard symbol may retrieve word variants: ((oecd environment) or (((world environment) or (lipid environment)))) working papers*.
