Exhaustive KNN
Exhaustive KNN is a vector search algorithm that calculates distances across all candidate vectors to return the exact nearest neighbors for a query. Teams use it to test vector relevance, produce exact nearest-neighbor baselines, or serve smaller vector workloads where accuracy matters more than approximate search speed. It is not HNSW approximate search, semantic ranking, a text analyzer, an embedding model, or a fix for poor chunking and low-quality vectors. In production, confirm index schema, vector dimensions, algorithm configuration, vector profile, query k value, exhaustive flag, latency, throttling, relevance test set, and comparison with HNSW results before treating the design.

A Facetable field is an Azure AI Search index field marked so the service can return facet buckets, counts, or filter choices for query results.

Azure AI Search index
An Azure AI Search index is the place where your application searches. It is not just a pointer to a database or blob container. It is a separate searchable structure with documents, fields, and rules for how text, filters, facets, semantic ranking, and vectors behave. If the index schema is wrong, the search experience feels wrong even when the source data is good. Developers and operators use indexes to make.

It can map fields, detect changes, crack documents, and run enrichment skills before writing searchable documents. It is useful when source data changes regularly.
