New Data Search capability we introduced last month, needed a server-side data indexing and data discovery mechanism, to enable fast data/insights searching. We benchmarked SolR and ElasticSearch and found SolR significantly faster and more robust in the area of NLP/ML, so went ahead and integrated SolR in Germain. 


  • Indexed 1million rows in less than 4 min using our own 3-year old desktop, without any tuning
  • Searched on this 1 million row is taking at the most 500ms
