Top SchoolJan Høydahl is a search solutions architect and owner of Cominvent AS with over 25 years of IT experience, specializing in the Apache Lucene ecosystem (Solr, Elasticsearch) and pragmatic delivery of search and big-data solutions. He blends deep hands-on engineering (Java, Kotlin, Python) with user-centered consulting, helping organizations turn data into actionable, efficient search services. An Apache Lucene/Solr committer, PMC member and former Solr PMC Chair, he contributes to core projects and ecosystem tooling—work that includes meaningful backend improvements to Solr and Dockerized Solr builds. His career spans R&D leadership and systems engineering from Ericsson telecoms to enterprise search at FAST, reflecting strong skills across OSes, languages and deployment environments. As a freelancer he pairs technical authority with independent advisory and training, often addressing deployment, permission and performance quirks that others miss. Based in Drammen, Norway, he brings rare institutional knowledge of open-source search combined with practical DevOps refinements demonstrated in notable repos like apache/solr and docker-solr.
