Indexing and searching are the two primary operations performed in Solr. Indexing is the process of adding content to a Solr index to make it searchable. But before you can index, you first need to set up Solr. The primary focus of release 5.0 was improving ease of use, which has made Solr setup process extremely easy. The steps are so simple that if you run Solr in schemaless mode, enabling Solr to dynamically guess the field type and define fields, the whole setup process can be performed in few minutes.
