Summary

We have successfully installed Solr as a part of Apache Tomcat server. We saw how to communicate with Solr using PHP and cURL but without using a library. We discussed a few libraries and concluded that Solarium is feature rich and an actively developed and maintained library. We were able to install Solarium and were able to communicate with Solr using PHP and Solarium library. We were able to see actual queries being executed on Solr in the Solr logs. We explored some features of the Solarium client library such as endpoints and adapters.

In the next chapter we will see how to use the Solarium library for inserting, updating, and deleting documents in Solr using our PHP code.
