<b>NOTE</b>: as of 2.4, it's possible to open a read-only
IndexReader using one of the static open methods that
accepts the boolean readOnly parameter. Such a reader has
better concurrency as it's not necessary to synchronize on
the isDeleted method. Currently the default for readOnly
is false, meaning if not specified you will get a
read/write IndexReader. But in 3.0 this default will
change to true, meaning you must explicitly specify false
if you want to make changes with the resulting IndexReader.
