The default search will find funding opportunity titles and sponsor names that match your query.
If you limit the search by 1 to 3 Categories, you can also search the sponsors' web pages. This searches all web content (not just keywords, titles and headings) for all those opportunities and announcements that fit any other criteria, so it may take a while to return results.
If also searching web pages, which can take a while, Funding Connections can display an alert when the search is complete.
