Scenario
Managing multiple indexes in a large document using the \f switch and XE (Index Entry) fields to categorize entries into separate index tables.
Observed behavior
Index entries appear in the wrong indexes, duplicate, or fail to display properly due to inconsistent field codes, complex document structures, or improper \f switch arguments.
Before you start

Ensure you toggle your field codes on so you can see the hidden XE and INDEX formulas, and always create a backup copy of your large document before making bulk modifications to index identifiers.

Solution 1Recommended

Verify Field Codes and Rebuild the Index

Manually inspect your index entries to ensure consistent identifier usage, then update or recreate the index fields to resolve conflicts.

When managing multiple indexes, the \f switch relies on exact matches between the INDEX field and the XE (Index Entry) fields. Inconsistent use of identifiers, such as using multi-letter codes instead of single-letter ones, or utilizing incorrect quotation marks, can break this link and cause entries to populate incorrectly.

1
Toggle field codes visibility

Press Alt+F9 (or Fn+Alt+F9 on some keyboards) to reveal all hidden field codes in your document, including the { XE } and { INDEX } tags.

2
Check switch arguments

Locate your XE fields and ensure the \f switch uses a simple, single-letter identifier enclosed in straight quotation marks (for example, { XE "Entry" \f "a" }).

3
Recreate the index

If the existing index is corrupted or pulling incorrect entries, delete it. Go to the References tab, click 'Insert Index', and set it up to track your specific identifier.

4
Update all fields

Press Ctrl+A to select the entire document, then press F9 to update all fields and regenerate the indexes from the corrected XE entries.

Quotation Marks in Fields: While curly quotation marks sometimes work in XE fields, it is highly recommended to use standard straight quotation marks for all field code arguments to prevent parsing errors.

Frequently Asked Questions

Why are my XE entries appearing in the wrong index?

This happens when the \f switch identifier in the { INDEX } field does not exactly match the identifier in the { XE } field, or if the identifier was accidentally omitted from the index entry altogether.

Should I use single-letter or multi-letter arguments for the \f switch?

It is highly recommended to use single-letter arguments (like "a", "b", or "c") for the \f switch. Multi-letter arguments like "aa" or "bb" can sometimes cause parsing issues in large, complex documents.

How do I view hidden XE (Index Entry) fields in my document?

You can toggle the visibility of all field codes by pressing Alt+F9. Alternatively, click the 'Show/Hide Paragraph Marks' button (the pilcrow icon ¶) on the Home tab to display hidden text formatting.

Do curly quotation marks affect field codes?

While some XE fields tolerate curly (smart) quotation marks, most field codes strictly require standard straight quotation marks. If your index is failing to build, replace any curly quotes with straight ones in your field parameters.
