Asset Search And Filtering

via “payload-based filtering with multiple field index types”

Qdrant - High-performance, massive-scale Vector Database and Vector Search Engine for the next generation of AI. Also available in the cloud https://cloud.qdrant.io/

Unique: Integrates field indexing directly into segment architecture with automatic index type selection based on field cardinality and query patterns, enabling filters to be applied during HNSW traversal rather than post-search, reducing candidates evaluated by 50-90% for selective filters

vs others: More efficient than post-filtering because index-aware pruning happens during graph traversal, whereas alternatives like Elasticsearch require two-phase search (filter then rank) or separate index lookups
