OCRed PDF can't be searched on ACS 7.4

[billydekid]

Hi, 

I have successfully installed Alfresco 7.4 community edition (with Ansible installation method) on my Ubuntu 22.04.

I have a small sample pdf which already OCRed (transform image to text) and I want this pdf file is indexing and searchable on Alfresco. But I can't search the text inside the document from the viewer (document page). 

Is there any steps should I perform/completed?

Thank you,

I'm sorry, it's my fault which I upload a broken OCRed pdf file, hence it was failed to index and searched.
