Yes! Use the search_format tool and specify the format parameter (e.g., 'maps', 'photos', 'audio') along with your query to get targeted results.

02

How do I get the full OCR text of a digitized document?

You can use the get_text_service tool. Provide the document segment path and set the full_text parameter to 1 to retrieve the complete OCR transcript.
