Complex search

• Because results must match every category you specify, it is easy to compose a search that returns no results.
• If that happens, simplify by removing some category terms from your search, or by choosing more general terms.
• Searching using a more general term, like mineral resources will return studies and datasets about the narrower terms associated with it, like critical mineral resources.
• The search results list will include a link that you can use to return to your search and modify it or bookmark it.
