Solr vs Elastic search. Quick comparison


Both search engines are based on Lucene, therefore they have a very solid base and in some respects similar functionality. Lucene is responsible for managing what is called an inverted index, so that search terms defined by the user can be found in certain documents of an unstructured nature, usually texts.


However, they have certain differences that we detail below.

Visualization and User Interface of Solr vs Elasticsearch

Elasticsearch, thanks to the ability that Kibana brings to it, has more ability to generate analytical reports and data exploration since Solr has traditionally focused on text searches. So if data visualization is critical, elasticsearch provides more capacity. However, it should be noted that Solr has been incorporating plugins that have increased its functionality in terms of viewing reports.

Solr vs Elasticsearch scalability

This is one of the main reasons why Elasticsearch was developed, so that you can better manage growth without losing quality. However, Solr has managed to improve its scalability thanks to the creation of SolrCloud and integration with Zookeeper.

Solr vs Elasticsearch customization

Solr is more customizable, and can be adjusted to suit the user's needs. The ability to customize Elasticsearch to suit the user's needs is more limited.
