About Optical Character Recognition (OCR)

The full text search has been enabled by a process called optical character recognition which looks at the groups of characters on the card image and converts the data into something that can be searched.

The fuzzy search means that even if the characters have not been correctly recognised the system can interpret the data and give you some results.

(If a whole book is being scanned the optical character recognition can be adjusted to allow for inconsistencies in the typeface e.g. an indistinct character, because it will occur throughout the document. Because our cards were typed and produced on many machines and by several methods this "learning" part of the OCR process cannot be used.)

The optical character recognition does not always recognise a word or term but the fuzzy search will display all near matches.
