Ok. I was able to conclude that the I am getting OOME due to my usage of HTML Parser to get the HTML title and HTML text. I display 10 results per page and therefore end up calling the org.apache.lucene.demo.html.HTMLParser 10 times.
I modified my code to store the title and html summary in the index itself and found out that the OOME problem is gone. I tested this with 256MB heap size. Thank you all for your valuable advice and help. Chetan Shah wrote: > > I am initiating a simple search and after profiling the my application > using NetBeans.
