Perhaps you should try some spelling variations:
lipid environment » grid environment, arid environment, hybrid environment
field environment » food environment, world environment, build environment
oecd environment » oecd environmental, covid environment, grid 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 (((field environment) OR (lipid environment)))) working papers.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((oecd environment) or (((field environment) OR (lipid environment)))) working papers".
• Adding a wildcard symbol may retrieve word variants: ((oecd environment) or (((field environment) OR (lipid environment)))) working papers*.
