About

The List Match extractor is one of the the simplest extractors used in Grooper. It is designed to return values matching one or more items in a defined list. This can be used to extract anything from field labels on a form or a list of names, to specific words and full phrases contained within a document. A List Match extractor returns an exact match including any spaces, numbers, punctuation, or special characters.

Unlike a Pattern Match, the List Match extractor does not use or require regular expressions by default, but regex can be enabled in the properties menu. Similar to a Pattern Match, suffix and prefix patterns can be added to help anchor the expression and limit the amount of false positives extracted.
