Some finer points
The basic method for producing indexes has been explained. There are, however,
a few subtle points that you may well encounter, especially if your work
is complicated.
Titles
Most indexes are based on titles. But sometimes you want a slightly different
title in the index than in the text. A typical example would be a case name
that begins ‘Re’. You want this in textual citations as Re Matter, but in the
index you want it listed as Matter, Re. To do this you will need to set the
indextitle field to the form you want used in the index.
Suppressing Indexing
There may be occasions when you want to suppress the indexing either of a
particular entry, or of a particular citation. 21
To suppress indexing of a particular entry whenever it is cited, set its
tabulate field to ‘trash’. This effectively means that it will never find its way
into any real index.
To suppress indexing of a particular citation, put the command \DNI
(which stands for ‘Do Not Index’) immediately before the citation. This is
mostly useful when you are intending to provide your own indexing entry
for the citation, and need to suppress the one that would be automatically
provided.
Adding index entries
Finally there are two commands you can use to insert index entries yourself.
The first is \indexonly. This will simply insert an index citation formatted
exactly as if you had cited a particular source, but without printing anything.
So, for instance, \indexonly[2]{ucta77} will insert an index entry for
section 2 of the Unfair Contract Terms Act 1977 into the index.
The second is to use the \index command directly. This can be useful
for more sophisticated things. You use it exactly as you would use it on any
other occasion. This is likely to be a rare occurrence: its most common use
will be for inserting a cross-reference (for instance to a ship’s name).
For example, suppose you have the following case (which also shows the
use of additional reports for listing in the index):
21 Of course, to suppress it in general, just don’t use the indexing option at all!
