问题
I intend to make a niche search engine. I am using apache-nutch-1.6 as the crawler and apache-solr-3.6.2 as the searcher. I must say there is very less updated information on web about these technologies.
I followed this tutorial http://wiki.apache.org/nutch/NutchTutorial and have successfully installed apache and solr on my ubuntu system. I was also successful in injecting seed url to webdb and perform the crawl.
Using solr interface at http://localhost:8983/solr/admin, I can also query the crawled results. But this is the output I receive.
.
Am I missing something here, the earlier apache-nutch-0.7 had a war which generated a clear html output like this.
. How do I achieve this... Or if anyone could point me to a latest tutorial or guidebook, highly appreciated.

A couple of things:
- If you are just starting, do not use Solr 3.6, go straight to latest 4.1+. A bunch of things have changed and a lot of new features are added.
- You seem to be saying that you will expose Solr + UI directly to general web - that's a really bad idea, as Solr is completely unsecured and allows web-based delete queries. You really want a business layer in a middle.
- With Solr 4.1, there is a pretty Admin UI and, also, there is a /browse page that shows how to use Velocity to do the pages backed by Solr. Or have a look at something like Project Blacklight for an example of how to get UI over Solr.

I found below link http://cmusphinx.sourceforge.net/2012/06/building-a-java-application-with-apache-nutch-and-solr/ which answered my query.
I agree after reading the content available on above link, I felt very angry at me. Solr package provides all the required objects to query solr.
Infact, the essential jars are just solr-solrj-3.4.0.jar, commons-httpclient-3.1.jar and slf4j-api-1.6.4.jar.
Anyone can build a java search engine using these objects to query the database and have a fancy UI.
Thanks again.
