The publications search will only return results for documents or pages containing, in their title or on the web page, ALL the search terms you enter.
EXAMPLE: If you enter the terms "Housing Policy Plan," results will only include documents or pages having at least those three terms in the title or on the page. For instance, results would include "Housing Policy Plan 2030," or "Housing Policy Plan 2040" It would not include results containing only the words "Housing Policy" or "Housing Plan."
