“Query meets latency and recall thresholds against benchmark” concerns Exact full scans miss API latency target; the reported problem instead is LIKE contains pattern scans large text columns. Keyword matches return expected documents efficiently.

“Chosen retrieval meets pre-agreed relevance and latency thresholds” concerns Latency metric alone says nothing about retrieval quality; the reported problem instead is LIKE contains pattern scans large text columns. Keyword matches return expected documents efficiently.

“Track failed conversions and vector schema changes” addresses the vector data column type situation—numeric similarity queries are slow and error-prone. The observed failure is: LIKE contains pattern scans large text columns. Monitor whether SQL full-text index populations keep pace with source updates and whether stoplist or language-setting changes reduce searchable terms. The original LIKE predicate is expensive on large descriptions; after introducing a suitable full-text path, stale population state or changed tokenization can cause missing matches even when queries still execute.

“Monitor feature changes and migration incompatibilities” concerns Vector feature support and preview status differ by platform; the reported problem instead is LIKE contains pattern scans large text columns. Monitor whether SQL full-text index populations keep pace with source updates and whether stoplist or language-setting changes reduce searchable terms. The original LIKE predicate is expensive on large descriptions; after introducing a suitable full-text path, stale population state or changed tokenization can cause missing matches even when queries still execute.

“Monitor recall loss after index changes” concerns ANN tuning could miss a few true nearest matches; the reported problem instead is LIKE contains pattern scans large text columns.

The original LIKE predicate is expensive on large descriptions; after introducing a suitable full-text path, stale population state or changed tokenization can cause missing matches even when queries still execute.

“Review index metric and query plan warnings” addresses the vector index metric selection situation—compatible ANN index may not be selected. The observed failure is: Semantic nearest-neighbor may return related but incorrect codes. Inspect exactness requirement and phrase specificity.

“Inspect vector norms and scoring requirement” concerns Magnitude dominates scores when direction matters; the reported problem instead is Semantic nearest-neighbor may return related but incorrect codes. Inspect exactness requirement and phrase specificity.

“Review corpus size, metric and exactness requirement” concerns Approximate index recall is unnecessary for this dataset; the reported problem instead is Semantic nearest-neighbor may return related but incorrect codes. Inspect exactness requirement and phrase specificity.

“Use supported VECTOR_DISTANCE ordering to compute exact pairwise distances” concerns Approximate index recall is unnecessary for this dataset; the reported problem instead is Semantic nearest-neighbor may return related but incorrect codes. Use full-text or equality search for exact regulatory identifiers.

Use full-text or equality search for exact regulatory identifiers.

“Implement supported SQL full-text catalog/index and CONTAINS queries” concerns LIKE contains pattern scans large text columns; the reported problem instead is Semantic nearest-neighbor may return related but incorrect codes. Use full-text or equality search for exact regulatory identifiers.
