These tips will give you the best results:

Format: You can convert .JPEG, .PNG, .GIF, or PDF (multipage documents) files.

File size: The file should be 2 MB or less.

Resolution: Text should be at least 10 pixels high.

Orientation: Documents must be right-side up. If your image is facing the wrong way, rotate it before uploading it to Google Drive.

Languages: Google Drive will detect the language of the document.

Font and character set: For best results, use common fonts such as Arial or Times New Roman.

Image quality: Sharp images with even lighting and clear contrasts work best.

Whenever the PDF is standard or low resolution (instead of high resolution) the search feature works as expected, both in Drive and within the PDF. But when the PDF is high-resolution, search only works within the PDF, and NOT in Drive.
