Index sort order with underscore (_)

Question

Hi.

According to the documentation, the default sort order for indexes is <$symbols><$numbers><$alphabetics> with hyphens, nonbreaking hyphens, en dashes, and em dashes ignored by default. Nothing about underscores, so they should be sorted on first, right? But they are not in my document. Example:

PaymentModule_Order_Head

PaymentModule_OrderPayment_Capture

PaymentModule_Order_Tabs

What I want to see is:

PaymentModule_Order_Head

PaymentModule_Order_Tabs

PaymentModule_OrderPayment_Capture

Is there an easy way to fix this so underscores have precedence over alphabetics? I've tried rearranging the building blocks every which way but nothing seems to work.

Looks like FM is also ignoring the underscores, so in order to force the desired sort order, you have to add a sort override key after the index entry in square brackets, e.g.

PaymentModule_Order_Head[PaymentModuleOrderHead]

PaymentModule_OrderPayment_Capture[PaymentModuleOrderZPaymentCapture] <--- note the "Z" to force the sorting further down the list. You could use other values depending upon what your other index entries are like.

PaymentModule_Order_Tabs[PaymentModuleOrderTabs]

Also, again depending upon what other index entries you have, you might be able to abbreviate such override keys to something like [PMOHead], [PMOZPaymentCapture]. etc.
