Haystack EU
Haystack EU is the European edition of the Haystack search relevance conference, jointly organized by OpenSource Connections and Plain Schwarz, held in Europe (Berlin). Like its US counterpart it is practitioner-focused on search relevance — ranking, Learning to Rank, evaluation, and semantic/vector search across Solr, Elasticsearch, and OpenSearch. Charlie Hull is closely associated with the European search-conference scene.
