# Learning about OpenSearch
<a name="learning"></a>

Although both Solr and OpenSearch are based on Apache Lucene, they have different features and architectures. Learning the fundamentals of OpenSearch is crucial when migrating from Solr.

Both the [managed Amazon OpenSearch Service](https://docs.aws.amazon.com/opensearch-service/latest/developerguide/what-is.html) and the [open source version of OpenSearch](https://docs.opensearch.org/latest/about/) have extensive documentation. AWS also offers  the following educational materials to help your teams gain practical experience.
