IndexReader.IsCurrent Method 

Check whether this IndexReader is still using the current (i.e., most recently committed) version of the index. If a writer has committed any changes to the index since this reader was opened, this will return
false
, in which case you must open a new IndexReader in order to see the changes. See the description of the
autoCommit
flag which controls when the {@link IndexWriter} actually commits changes to the index.

Not implemented in the IndexReader base class.
