OCR content in AtoM's search

[Cássio Felipe de Oliveira Pires]

Hi, everyone

Is there a way to block AtoM from displaying search results based in OCR text? This can be done globally (like removing pdftotext) or is it possible to block the OCR indexation of specific digital objects?

Thanks!

alternatively, is it possible to remove from AtoM the 64K of OCR text from a digital object that has been indexed into the database?

Hi there, 

Going forward: yes, if you remove pdftotext, then this block of code that indexes the OCR layer should not activate, meaning your future PDF uploads will not be indexed. 

For those already indexed in your system: 

We could try to use SQL to delete the OCR text from the database. As always, please proceed at your own risk and make a backup first!

If you want to delete ALL existing OCR transcripts from your AtoM database, try the following query: 

• DELETE FROM property WHERE name='transcript' AND scope='Text extracted from source PDF file\'s text layer using pdftotext';
  

Hope that helps!
