We use MMapdirectory impl. in our search application. Occasionally we need
to do a full indexing by dropping entire directory contents. How does
re-mapping work with MMapDirectory as the directory contents are going to
replace with new ones? is this going to be seamless or an application
restart
searching and indexing apps run in diffrent jvms. we use lucene 4.7 and
using the default openmode.
For full indexing, we use java.io.File.delete() to recursively delete index
directory contents. will remapping cause any issues in this case if I dont
use options you suggested?

Just open a new IndexWriter with OpenMode.CREATE. It will replace the index.
Or if you already have an IW open, use deleteAll.

It's fine if writer and reader are in separate JVMs.
You really should not rm -rf yourself.
It's better to let Lucene's do it, e.g. it's transactional at that
point so that if your new IndexWriter (that deleted all docs) crashes
before it could commit, the old index is still intact. It also

Appreciate it Mike. That answeres it all.
