Ask HN: Are Lucene/Solr/ES Still Used for Search?
From my experience, yes. Lucene is a &quot;production&quot; state of art library and Solr&#x2F;Elasticsearch is very used in many scenarios.<p>This expertise is very on demand.<p>My company personally migrated from ElasticSearch to <a href="https:&#x2F;&#x2F;vespa.ai&#x2F;" rel="nofollow">https:&#x2F;&#x2F;vespa.ai&#x2F;</a> and could not be happier. Faster and way easier to maintain a cluster. The &quot;Application Packages&quot; feature present in Vespa opened many opportunities to improve our product( Curiously we use Lucene inside our custom application for a &quot;Search map&quot; functionality, for something like that <a href="https:&#x2F;&#x2F;www.lexisnexis.com&#x2F;en-us&#x2F;products&#x2F;lexis-advance&#x2F;search-term-maps.page" rel="nofollow">https:&#x2F;&#x2F;www.lexisnexis.com&#x2F;en-us&#x2F;products&#x2F;lexis-advance&#x2F;sear...</a> ) . I highly recommend it!
