Minimum Requirements for Text Search

As Knowable receives and processes documents, those documents will be available for search initially via upload metadata. Once the document has completed Knowable’s optical character recognition (“OCR”) processing, documents can be located via text-based search leveraging the OCR output. 

Documents must meet minimum OCR Quality Requirements for document quality for OCR processing.

The OCR Quality Requirements include, but are not limited to:

1. Minimum DPI of 300
2. Characters must not be skewed more than 1 degree
3. Document must contain enough contrast between text and background
4. Document must not contain water marks or other text over the content
5. Characters must be sharp without significant blur

Document OCR for tables and handwriting are not supported, and OCR may not be available for all languages.

Please note that if you upload password protected or encrypted files, Knowable Insights may not be able to search them.
