Direct link to above movie tutorial (21 seconds): Watch Google Search Tip: Search Within a Site
OUR TUTORIAL:
Simply go to https://www.google.com in a web browser (not the Google app) and Paste this text in the search field as seen in my below example:
- site:americanindianreporter.com ROSE SALGADO
For example (click to test) to search our newspaper archives for "ROSE SALGADO": site:americanindianreporter.com rose salgado
If you clicked on my example, notice all the search results are limited to the "site:americanindianreporter.com" and the key words "ROSE SALGADO".
Just change only the key words (I set up in caps) to start a new search....
After you locate and open a PDF -- search the PDF for your key words using Control+F (Windows) or Command+F (macOS) in the usual manner you use to search documents.
