Abstract
A method and apparatus are provided for indexing electronic documents that include one or more visible text portions and one or more non-visible text portions. The method includes the step of identifying an electronic document. Once the electronic document is identified, a set of words is selected from a particular tag type that is associated with one or more non-visible text portions of the electronic document. Each word in the selected set of words is compared with words in the one or more visible text portions of the electronic document. An index word set is then determined for the electronic document based on matches between words in the selected set of words and words in the one or more visible text portions of the electronic document.
