What should you do after conducting an advanced search to limit results to PDFs?

To limit search results specifically to PDF files after conducting an advanced search, you would use the 'filetype' operator directly in the search box. By inputting 'filetype:pdf' as part of your search query, you instruct the search engine to filter results, returning only links to documents that are in PDF format. This targeted approach helps refine your search and ensures that you efficiently find the specific type of content you are looking for without unnecessary results from other file formats.

Using the 'filetype' operator demonstrates a practical application of advanced search techniques, allowing users to harness the power of search syntax to enhance their search precision and efficiency. This can be especially useful in academic or professional settings where specific file types, such as PDFs, are often required for documentation or reference.
