Daily Dose: Apache Releases Version 3.1.0 of Solr and Lucene

· Java Zone

Microservices! They are everywhere, or at least, the term is. When should you use a microservice architecture? What factors should be considered when making that decision? Do the benefits outweigh the costs? Why is everyone so excited about them, anyway?  Brought to you in partnership with IBM.

The newest release of Solr and Lucene are ready for action!  Project leaders have changed Solr's version number scheme to mirror Lucene's. Both the Solr 3.1.0 and Lucene 3.1.0 release have many new features.  Here are three Lucene 3.1.0 release highlights from Lucid's official release notes:

* ReusableAnalyzerBase makes it easier to reuse TokenStreams
 correctly.

* Improved Analysis capabilities: Improved Unicode support, including
 Unicode 4, more friendly term handling (CharTermAttribute), easier
 object reuse and better support for protected words in lossy token
 filters (e.g. stemmers).

* ConstantScoreQuery now allows directly wrapping a Query.

And three highlights from the Solr 3.1.0 release…

* JSON document indexing

* Numeric range facets (similar to date faceting).

* New spatial search, including spatial filtering, boosting and sorting capabilities.

jQuery 1.5.2 Ready to Go

Google +1: Making Web Search Social

With the Google +1 search feature, Google has taken search into the social realm. Much like Facebook's "like" option, Google +1 allows users to add their stamp of approval on sites that appear in their search.  Google assumes that people are bound to "like" the same types of sites as their friends.  +1 lets you see which sites your friends have voted up.  Another, more questionable, application of the Google +1 feature is its potential to improve Google's ad targeting endeavors.  In the future, Google hopes to integrate Google +1 with its apps.

OpenNebula 2.2 Open Source Cloud Software

OpenNebula 2.2, code named Cat's Eye, has been released.  This new version of OpenNebula has an improved user interface and several new features.  A graphical user interface (GUI) is provided by Sunstone. Users can use the GUI to manage Infrastructure As A Service within the browser.  An overall fault tolerance increase has been achieved in OpenNebula. Should a server fail, the system is automatically rebuilt on another server.  Monitoring large server farms is easier with the Ganglia monitoring system.
