Then again you could revisit the decision to use Lucene and look at OSS Network 
Management solutions. Of course if your events aren't under governance of some 
kind, I can understand why you want a search engine. FWIW: I can't imagine a 
professional system engineer at AOL/MicroSoft/Comcast or any other place I've 
worked not looking at me sideways if I built alerting that needed a search 
engine instead of industry standard (proprietary and open source) system 
engineering methods.

Hi Prathib,

As this is a monitoring application, have you considered a stored search 
solution? We created Luwak (based on Lucene) for exactly this purpose:
https://github.com/flaxsearch/luwak - note that Luwak will (very shortly) build 
with Lucene 5.3 rather than the fork we created, as the requisite features are 
now in a release build of Lucene.

Cheers

Charlie
