Mike,
If I was to look at this from a totally Logical stand point - I would
think the Indexes are ONLY update if you update a field in a record
where that field is contained in one or more of the Indices.
However, Why not do a simple test - and generate your Own answer!??
Take a chunk of the data from your table in question - or even take a
copy of the Whole thing, along with the Indices, drop into another
folder. Then - simply do some updates based upon your criteria below -
and then you can confirm Exactly what happens!
Right???
:-)

Question for you legends of the Fox (data):
Say Table1 has "X" number of indexes. Program code does something
like the following:
IF Condition1 THEN
REPLACE Field1 with SomeValue in Table1
ENDIF
IF Condition2 THEN
REPLACE Field48 with Datetime() in Table1
ENDIF
Are each of the "X" indexes updated for each replace, even if those
indexes do not include any reference to Field1 or Field48, or only
indexes that are affected by the data value change?
I understand that ADDing and DELETEing records updated all indexes; I
would think the UPDATEs--regardless of what fields updated--would
cause index updates for every indexed field on every update as well.
