More sophisticated indexing is available by loading the makeidx package.
All occurrences of the technical names can be easily found, starting from any other. When this is done incorrectly, the resulting link will be to the segment where the indexed item occurred, rather than staying within the Index. Since use of section-names, as the text for hyperlinks, can lead to a very long and cumbersome Index, especially when single items have been indexed many times, a further feature is provided to obtain a more compact Index. The differences are as follows. The Index includes a legend of these prefixes, each giving the title of the leading page from the segment, as a hyperlink to the place on that page where its child-links are displayed.
