What should I do if Automatic Profile Selection does not identify the document as expected?

<When different documents are detected as the same document>

Set a higher level of [Accuracy Level].

Differences between documents will be detected more finely, and documents are likely to be detected as different. 

 

<When the same document is detected as a different document>

Set a lower level of [Accuracy Level].

Slight differences in documents will be considered to be errors, and documents with the similar layout are likely to be detected as the same.
