What this post added

GlassDollar migrated from Elasticsearch to Qdrant for their high-recall sourcing product. This migration improved retrieval speed, reduced infrastructure costs by 40%, and enabled more effective query expansion. The system leverages the Qdrant Node.js SDK for integration within their existing Node.js/TypeScript backend services. The improved retrieval quality led to a 3x increase in user engagement (bookmarks).
