All button in the Mark Index Entry dialog box, Word searches for each occurrence of the word or phrase you've entered and marks it as an index entry. The search is case sensitive. You may have to run the search twice to pick up all the entries that should be grouped together, then edit the index entries to make them consistent. The same is true of singular and plural entries. If you run it too early, and then run it again later, Word remarks the entries that are already marked.
