<para>
If you are using MongoDB version 1.3.2+, you can create indexes in the
background while other operations are taking place. By default, index
creation happens synchronously. If you specify &true; with this
option, index creation will be asynchronous.
By default, index creation is a blocking operation and will stop other
operations on the database from proceeding until completed. If you
specify &true; for this option, the index will be created in the
background while other operations are taking place.

<warning>
<para>
Prior to MongoDB 2.1.0, the index build operation is not a background
build when it replicates to secondaries, irrespective of this option.
