- 3. Summary Why Create Search Applications? What Solr is What Solr is not Why choose Apache Solr?

- 4. Reasons to Create Search Applications Users have been spoiled by Google and other search engines. Users are used to navigation using a search box. If unable to locate information immediately, they assume it's not there. Less patience when attempting to look for information Certain customer service tools may not have relevant navigation Information needs to be located immediately
- 5. Reasons to Create Search Applications Reduce the amount of time it takes to locate information Make products and services more accessible to customers Increase time spent by visitors on web application Save time, Save money Increase employee efficiency (CRM applications) Improve user experience on web application Increase revenue and increase profit
- 6. About Solr Solr is written in Java Standalone full text Search Server within servlet container Uses the information retrieval library Lucene at its Core Joined Apache Incubator in January 2006 First major release in December 2006 Latest stable release is 1.4.1 - June 2010 Next major release 4.0 http://lucene.apache.org/solr/
- 7. What Solr is NOT Solr is not a wrapper around Lucene Solr is not a RDBMS
- 8. What version should I use? I am confused … The current version of Apache Solr is 1.4.1 Why is there both a 1.5 and a 3.x anyway ? Not to mention a 4.x ? 1.5 is pre lucene/solr merge (very unlikely to ever be released) 3.1 is the next lucene/solr point release (3x branch in svn) 4.0 is the next major release (trunk in svn)
- 9. Why Choose Apache Solr? • Solr is FREE and Open Source (released under Apache License) • Advanced Full Text Search Capabilities absent in an RDBMS • Optimized for High Volume Web Traffic • Standards Based Open Interfaces - XML,JSON and HTTP • Comprehensive HTML Administration Interfaces • Server statistics exposed over JMX for monitoring • Scalability - Efficient Replication to other Solr Search Servers • Flexible and Adaptable with XML configuration • Extensible Plugin Architecture • Because a Voice in my head told me to • All of the above
