Qdrant is a proven choice for image similarity search. Our team has delivered hundreds of image similarity search projects with Qdrant, and the results speak for themselves.
Qdrant is purpose-built for high-performance vector similarity search, making it ideal for image retrieval systems that need to find visually similar images across millions of items in milliseconds. Its support for multi-vector storage lets you combine CLIP embeddings (visual features) with metadata vectors (color histograms, texture descriptors) for richer similarity matching. Qdrant's payload filtering applies hard constraints—brand, category, price range—before vector comparison, ensuring results are both visually similar and business-relevant. The Rust-based engine delivers consistent sub-20ms query latency even at scale.
Store multiple vectors per image—CLIP for semantic similarity, color histograms for palette matching, and texture descriptors for material similarity. Query with weighted combinations for nuanced visual search.
Apply payload filters (category, brand, price range, availability) before vector comparison. This ensures results are not only visually similar but also meet business constraints without post-filtering.
Qdrant's Rust engine with HNSW and quantization delivers sub-20ms searches across 100M+ vectors. Memory-mapped storage handles datasets larger than RAM without sacrificing latency.
Bulk upload millions of image vectors during initial indexing, then add new images in real-time as they're uploaded. Dynamic index updates mean new products appear in search results instantly.

Schedule a CallUse Qdrant's named vectors feature to store both CLIP and color histogram vectors per image. At query time, weight them differently based on search intent—80% CLIP + 20% color for "find similar style" and 20% CLIP + 80% color for "find similar colors" searches.
Qdrant has become the go-to choice for image similarity search because it balances developer productivity with production performance. The ecosystem maturity means fewer custom solutions and faster time-to-market.

A Qdrant image similarity system preprocesses uploaded images through a pipeline that generates CLIP embeddings for semantic similarity, extracts color histograms via OpenCV, and computes perceptual hashes for near-duplicate detection. Each image is stored in Qdrant as a point with a named vector for CLIP features and payload fields for metadata (category, brand, dimensions, upload date). Search queries accept either an image upload (vectorized on the fly) or a product ID (fetching the stored vector).
The query combines vector similarity with payload filters—a fashion search for "similar dresses under $100 in blue" uses the CLIP vector for style similarity, a color filter on the histogram payload, and a price range filter. Qdrant's recommendation API takes positive and negative example images to refine results. Duplicate detection runs perceptual hash comparison as a pre-filter before CLIP similarity, catching exact and near-identical copies efficiently.
The system handles 100M+ images with scalar quantization reducing memory by 4x while maintaining 98% recall.
