Workspace Node: Text Mining - Specifications - Delimiters Tab
In the Text Mining node dialog box, under the Specifications heading, select the Delimiters tab to access options to "bracket" the portion of the text in each document that you want to index. This is useful when you are processing structured narratives, e.g., standard accident reports, where the narrative of what happened is always contained between the headers "Description of accident/incident" and "Number of persons injured"; in this case, you could specify the former as the Starting phrase and the latter as the Ending phrase, and only parse (process and index) the text that is found between those headers in each accident report.
