Apache Solr is losing ground due to a shrinking maintainer base, ZooKeeper dependency, real-time indexing limitations, and gaps in vector/ML search. This guide compares five migration targets: Elasticsearch, OpenSearch, Typesense, Meilisearch, and Algolia. Elasticsearch and OpenSearch are the closest replacements, sharing Lucene foundations and offering richer ML, real-time, and analytics capabilities. Typesense and Meilisearch suit simpler, smaller-scale use cases. Algolia is fully managed but costly and creates vendor lock-in. Migration effort ranges from 2–8 weeks for Elasticsearch/OpenSearch (partial schema automation available) to full rewrites for the others.
