Expert: returns an IndexReader reading the index in the given Directory, using a specific commit and with a custom {@link IndexDeletionPolicy}. You should pass readOnly=true, since it gives much better concurrent performance, unless you intend to do write operations (delete documents or change norms) with the reader.
