You can do this by adding (or editing) XE (index entry) fields manually.
Display hidden text (to see and edit the XE fields). Existing XE fields
will
display similar to this: { XE "entry:sub-entry" }.
To add a level to an existing XE field, type another colon and another
word
to create more levels. For example: { XE
"entry:sub-entry:sub-sub-entry" }.
Update the index.
To manually create XE fields, press Alt+F9. Word inserts field
delimiters,
{ }. Just type the necessary code.
Here's more on the syntax of the XE field (from Help at
http://office.microsoft.com/en-us):
********************************************
Field codes: XE (Index Entry) field
{ XE "Text" [Switches ] }
Defines the text and page number for an index entry (index entry: A
field
code that marks specific text for inclusion in an index. When you mark
text
as an index entry, Microsoft Word inserts an XE (Index Entry) field
formatted as hidden text.). You insert an XE field to define an item to
include in the index (index: A list of the words and phrases that are
discussed in a printed document, along with the page numbers they appear
on.).
The XE field is formatted as hidden text (hidden text: Character
formatting
that allows you to show or hide specified text. Microsoft Word indicates
hidden text by underlining it with a dotted line.) and displays no
result
in
the document. To view this field, click Show/Hide .
Security Because content that is formatted as hidden text can easily be
made visible, do not use hidden text formatting to keep sensitive
information private.
Instructions
"Text"
Text you want to appear in the index. To indicate a subentry (subentry:
An
index entry that falls under a more general heading. For example, the
index
entry "planets" could have the subentries "Mars" and "Venus."), include
the
main entry text and the subentry text, separated by a colon

).
Switches
\b
Applies bold formatting to the entry's page number. The field { XE
"Highlighting text" \b } displays the entry as "Highlighting text, 23"
in
the index. The switch removes bold formatting if the index style (style:
A
combination of formatting characteristics, such as font, font size, and
indentation, that you name and store as a set. When you apply a style,
all
of the formatting instructions in that style are applied at one time.)
for
the entry is bold.
\f "Type"
Defines an entry type. The entry for the field { XE "Selecting Text" \f
"a" } is included only in an index inserted by the field { INDEX \f
"a" }.
The default entry type is "i."
\i
Makes the entry's page number italic. The field { XE "Finding text"
\i }
displays the entry as "Finding text, 23 " in the index. The switch
removes
the italic formatting if the index style for the entry is italic.
\r Bookmark
Inserts as the entry's page number the range of pages marked by the
specified bookmark (bookmark: A location or selection of text in a file
that
you name for reference purposes. Bookmarks identify a location within
your
file that you can later refer or link to.). The field { XE "Selecting
text"
\r SelectingText } displays the entry as "Selecting text, 20-25" in the
index.
\t "Text"
Inserts the text in place of a page number. Enclose the text in
quotation
marks. The field { XE "Highlighting" \t "See Selecting" } displays the
entry
"Highlighting, See Selecting" in the index.
\y
Specifies that the subsequent text defines the yomi (first phonetic
character for sorting indexes) for the index entry.
Note This switch can be used if you have at least one East Asian
language
enabled.

I know this may be an easy question, but here goes...
I'm creating an Index for my document (I'm using Word 2007). I know I
can
create a 2 level index, but I'd actually like to go another level or 2.
How do I do that? I've played around entering the code, but have been
unsuccessful.
Any help would be appreciated.
Thanks
