Some pdf can't be indexed

Hello,
With some pdf, the result of the indexation via fscrawler is an empty content field (see below).

Any idea?
Thanks.

Could you share your PDF document? You can DM it to me.

@Thierry_Pasqualini So the document is an image and does not contain text.
The only way to extract text from it is to configure OCR.

Have a look at https://fscrawler.readthedocs.io/en/fscrawler-2.5/user/tips.html?highlight=ocr#ocr-integration
