If you are into photography and Nikon, I am sure you know Nikonians.org website (if you don’t, then you have to know that you are really missing out on something, don’t waste your time and check them out :) ). The site has its own search engine called NikoScope ® and it is available at
I have participated in the creation of this website and I enjoyed it A LOT. Whole site is written in Java with the help of Lucene indexer using modern technologies like JSF, JBoss SEAM, Google Guice and EJB3. Last week, we have released a new version which brings many new features like ability to add a Nikonian into your buddies or to see other fellow Nikonians on a map. You can even see Nikonians that are not further than e.g. 100 miles – all you have to do is to use the inRadius operator like this.
Of course, you have to be a member of Nikonians.org to use these features. There is also official Nikonians blog post about this release. Enjoy!
