Vector similarity search from basics to production with Redis VSS
The problem
Traditional encoding methods like one-hot encoding become too sparse and computationally expensive for large vocabularies, making similarity search impractical at scale; developers lacked a clear path to production-grade vector search.
Workflow diagram · grounded in source
1
Create vector embedding
ai_action
“Audio, video, text, and images can all be represented as vector embeddings”
2
Store vectors in Redis
integration
“It allows developers to store a vector just as easily as any other field in a Redis hash”
3
Index creation
integration
“Indexes only need to be created once and will automatically re-index as new hashes are stored in Redis”
4
Similarity search query
ai_action
“we need to compare the distance between our query vector embedding and the vector embeddings in our dataset”
5
Hybrid query filtering
validation
“all of the existing RediSearch features like text, tag and geographic based search can work together with the VSS capability”
6
Return similar results
output
“The hybrid search attributes can be set for both gender and category of product such that when a vector search is performed, the returned items are filtered by those tags”
Reported outcome
Redis VSS enables low-latency vector similarity search over tens of thousands to hundreds of millions of vectors, supports hybrid queries combining vector and traditional search, and is demonstrated in a live Fashion Product Finder application.
