Search engines

• Elastic Search / Open Search - uses something called Lucene under the hood. Powerful but hard. Free and open source. Can run in docker. Much Setup required.
• Algolia - search as a service. Expensive and seems less suited for filtering. Powerful. Faster than elastic. Cannot run in docker. Little setup required.
• Meilisearch - simpler?
• SOLR - Also uses Lucene.
• Typesense - simpler?
• lnx - small Rust thing. Fast? Not recommended
