level 3: structured interaction
Qdrant is an open-source vector database and search engine designed for storing and querying high-dimensional vector embeddings. It allows you to perform fast similarity searches, finding the most relevant vectors to a given query vector. You can use Qdrant to build applications like semantic search, recommendation systems, and image or video similarity matching by storing and searching vector representations of your data.
