This article is intended for PSIcapture Administrators.
Regular Expressions, sometimes shortened to Regex, are used throughout many areas of PSIcapture to customize and fine-tune the results recognized through OCR, Character Filtering, and more. Regular expressions can assist in a large variety of tasks that relate to sifting through document metadata for the information that suits your business needs. In many cases, well-crafted Regular Expressions can save time and energy when processing workflows, since they can account for variables such as page distortion, similar character recognition, and even ensure that only specific character sets can be matched, such as Alphanumeric or Numeric filters. This also prevents a build up of excessive exceptions batches, increases Classification matching rates, and generally tweaks a Capture Profile to produce the best possible results. The article below states how to store global Regular Expressions through the self-named tab on the Configuration root of PSIcapture.
