Greetings @MIS FUJIHAYA

Thank you for reaching out to us through our Community Forums!

Could you please provide the version and complete build of your Nitro PDF Pro? This information can be located under the Help tab > About Nitro Pro. 

Also, aside from this PDF file, do you experience the same behavior on other PDF files?

If possible, please share a copy of this PDF file so we can investigate and see if the issue can be reproduced on our end. 

Kind regards,

Hi Nitronaut,

I used a latest trial version of NitroPro but we are planning to buy a product soon. We want to know how it happens that same words in the same documents can't read on OCR function.

And what you should advise to us for using the OCR Function.

Please see the link below for the PDF copy. Drawing Link

Hello @MIS FUJIHAYA

The PDF document appears to be a scan document an OCR needs to be executed in order to search for the text. For this type of document, the OCR in Nitro PDF Pro needs some tweaking in order to make all the MCCB text appear in the search results. To tweak OCR, open the document in Nitro PDF Pro then go to File > Preferences. Under OCR, I set the following:

After that, click Apply then OK to save the settings. 

To OCR the document, go to the Review tab > OCR then select 'Make Searchable and Editable'. Click OK to start the OCR process. 

Here the result of the OCR'd document where all MCCB appear in the search results.

Additional:

if I run OCR twice or more. it will generate the same but with the old one that why they look like added new words on search bar.
