Keeping track of modifications will have to occur outside of Lucene.
What you could do is check the file's metadata, particularly creation
date or modification date, and only index (or reindex) files based on
these values.

For example:
1. Created today: Fresh index
2. Created yesterday, modified today: reindex
3. Created yesterday, modified yesterday: no indexing needed

Thanks Jason, my basic need is to search for Date and Time ranges of
For instance, I'd like to find all files on my local file system which
modified in April 2011. 

My concern is that I don't know what files are new or modified when
a directory. 

Many thanks for your help!
