When I was deciding which DMS to use I tried Knowledge Tree, Owl Intranet Knowledgebase, OpenKM Document Management, and Xinco. I chose Logicaldoc because it had great documentation for getting the product installed compared to the other projects, it worked with Postgres, and it used technologies that I liked such as Lucene, Hibernate, and the spring framework. The team has been very quick about responding to questions that I ask as well as providing the information necessary to mitigate any problems that I had. This is a great project and I really enjoy using the product. The search functionality is so FAST!! The tag capability is also really cool. The employees at my office also really enjoy the searching function. No more using Windows search to search the network share because Logicaldoc is now used to manage all the documents!
