Update in the index is done as delete and insert, so there is no chaining.

I've been asked to create an index which combines two fields, date & location.
For reasons I don't really want to explain, we need/desire this index to be in the order of date, location. The minor gotcha is that while location will be populated at the time the record is created, the date field is not updated until a later point in time. This date is a document print date. So this date field will be going from a NULL value to a non-null value. I recognize that this can result in record chaining in the data table. In thinking about this, I realized this could have a similar affect within the index. However, I've never read anything about index chaining.

Do/can indexes chain?
Should I be concerned about this?
