ADAM Indexes - Default v.s. Containerized

I have searched high and low on the Microsoft site and through google, but
have yet to find a definition for Containerized Searches under ADAM. When you
bring up an attribute in the ADAM Schema Snapin, there is a checkbox to
"Index this attribute in Active Directory"
At the bottom of the tab is another setting with a check box:
"Index this attribute for containerized searches in Active Directory"

My initial thought was that the first was equivalent to an Equality search
and the latter is a substring search, but I don't believe this is quite right.

Any thoughts?

Thanks,
Craig Gilmour

It creates an index optimized for one-level queries.

If you need to index to be optimal for medial or tuple queries (wildcard is at
the front or in the middle of the string versus the end of the string) you MAY
want to enable tuple indexing. Tuple indexing is a bit expensive so you want to
test your DIT growth before applying in production.
