Hi Anil,
If with "Application" you mean an external / remote Application then
there's no such pre-built mechanism to do that.

The event is not notifies "in" your application or "to" your application.
Solr knows nothing about it.

Specifically, event listeners allows you to do something when a given event
happens...what exactly is "something" it's up to you; for instance you
could (asynch) send a http message to your API, send a message to a queue,
send a GCM message to some mobile device, or in general: everything :) but
again, this is up to you.
