Provided are techniques for dynamically mapping zones. For a file and a field, while receiving text characters, possible terms for the text characters are provided by querying an index. In response to receiving selection of a possible term from the possible terms, each occurrence and position of the selected term in the file is determined. In response to selection of an occurrence and position of the selected term, the file is marked to identify the selected occurrence at the position in the file. The selected term and the position are associated with the field for any other files that match a type of the file.
