# OCR Support for Scanned Documents

Content indexing and entity detection for scanned documents is supported for scanned documents in PDF format with the following attributes:

- English language documents

- Typewritten text including text created by dot matrix printers and typewriters

- Images that include text

- Documents with up to 50 pages

The scanned document is processed by using optical character recognition (OCR).

## Considerations

When optical character recognition (OCR) is performed on scanned documents, the following considerations apply:

- The quality of the original document affects the accuracy of the OCR process. For example, paper documents that are oxidized or discolored may not be processed.

- Dot patterns behind text affect the accuracy of the OCR process. For example, text created with a dot matrix printer with a dot pattern behind it may not be processed.

- Handwritten text is not supported.

## Verification

You can use the Collection Report to view entity detection failures from a data source that includes scanned documents. For information about the Collection Report, see Viewing the Collection Report.
