Lucene & Solr Year 2011 in Review

I much prefer reviews to predictions. Moreover so when there are so many worthy things to be mention as what Lucene and Solr have accomplished in 2011:

  • Near Real-Time search (freshly added documents can be immediately made visible in search results)
  • Field collapsing or result grouping
  • faceting module
  • language support

Plus the promise of the SolrCloud:

In short, SolrCloud will make it easier for people to operate larger Solr clusters by making use of more modern design principles and software components such as ZooKeeper, that make creation of distributed, cluster-based software/services easier.  Some of the core functionality is that there will be no single point of failure, any node will be able to handle any operation, there will be no traditional master-slave setup, there will be centralized cluster management and configuration, failovers will be automatic and in general things will be much more dynamic.  

On the other hand, last December LinkedIn open sourced IndexTank a real-time fulltext search-and-indexing system. Some of its features will definitely sound interesting to Lucene and Solr users.
