In this chapter, we covered details about the search service in Alfresco. In Alfresco 5.x, searching is supported by the Solr4 search engine. There are various advantages to this new search engine: it is scalable, robust, conducts a fast search, and its performance is better. It polls Alfresco at certain intervals to track the new changes and re-index the data. Solr4 uses an asynchronous mode of indexing. You can also set up the replication of Solr servers via a master slave configuration. Solr4 provides its own admin console for administrators to monitor and troubleshoot the health of the server.
In the next chapter, we will cover details on permissions and roles in Alfresco. It will also provide details about integration with third party central authentication tools like LDAP.
