INDEXING SUBJECT-LOCATING METHOD

A determination is made as to whether or not each word of a segment of a body of text is included in one or more multi-word subjects of a list of subjects included in the text. If a subject word is found, a further determination is made as to whether or not all words of the subject are included in the same segment. A subject, as to which all words are in the same segment, is associated with text-locating indications for indexing purposes. Routines are also shown for updating a window portion of a textual manuscript for indexing purposes, searching a word list for matches and forming an active list for words which match, performing approximate root matches, and determining from an activated word match which subjects of a subject list are found in their entirety in a manuscript text.
