To develop a natural language search, use terms that you might use when describing your research topic to another person.

Example: To find articles about efforts in the fast food industry to use recyclable packaging, you might use this search:

What efforts has the fast food industry made to use recyclable packages?

Or, you can use just the most important terms and phrases, in any order.

recycle package fast food

See Advanced Natural Language Search Options to learn about additional options that may enhance the search.
