I’m in the process of upgrading Community Server 2008.5 to Telligent Community and so far I’ve been impressed with the way Telligent Community features are aligning. I was a big supporter for Chat in the earlier public Community Server road maps but never realized how lacking Search was. One major change in Telligent Community is the decoupling of Search and new requirement to install Solr. Once you get over the fact that a .NET product (i.e. Telligent Community) needs Java and Tomcat in order for search to work, you are left with a very, very powerful search product. Seriously, Solr, has just made Telligent Community an even more compelling product for the enterprise.
Someday, Telligent may revert to using Microsoft Search Server, or return to the days of affordable pricing, or open source Graffiti CMS on CodePlex, or ensure that you don’t get hit by some weird licensing message on your site (e.g. This license for Telligent Community is not authorized for use on this host name. You can access the site by opening it up directly on the server that is running the site. You can also manage your license by clicking here. Seen on the http://winmodevcamp.org/ page earlier today) but, until then, revel in the power of Solr.
