About Apache Solr Search

The search business is evolving and those developing capabilities in enterprise search and custom website search have two choices: buy or build. First, offerings from Google Custom Search and Amazon CloudSearch and a few other players offer a managed search option. The second option is to build a custom search application using the open-source Lucene search library and customize it with Apache Solr search or Elasticsearch.

Any comprehensive review starts with a test environment on a local server in what is called standalone mode in Solr. Next, to plan for increased search volumes and a move to production it is important to review distributed search in Apache Solr in SolrCloud mode.

In this Solr Reference we start with the main Solr command line script called using bin/solr from the directory where Solr was installed. It offers 12 commands used for Solr search administration.

From there, posting data to an index, modifying configuration files and learning how the Apache Lucene Solr combination of tools analyzes the data becomes relevant. And last, bringing a custom search application to the production environment is the big payoff.

If you are interested in a linear approach to learning Solr we also offer free tutorials on this website and on our YouTube Channel. Happy searching!
