Vectors & similarity search
Evaluate with evidence
Measure vectors and similarity with denominators, slices, and gates chosen before seeing results on the internal FAQ semantic search.

Metrics
Track for vectors and similarity: recall@k, precision@k, abstain quality, ID-slice recall. Report fractions like 36/40, not vague quality adjectives. Segment by language, plan tier, document length, or other slices that matter for the internal FAQ semantic search.

Protocol
Freeze inputs and neighboring versions while evaluating vectors and similarity. Change one control. Pair results case by case on the internal FAQ semantic search. Define hard gates (severe errors, privacy, latency) before the bake-off. Use deterministic checks where possible; humans for nuance; model judges only with calibration against gold.
Numeric reminder for vectors and similarity: cos(a,b)=(a·b)/(||a|| ||b||)=(1×2+2×4)/(√5×√20)=10/10=1

Make it operational
Resist adding a twelfth metric before the first three for vectors and similarity on the internal FAQ semantic search have owners. This workload improves faster when a small scorecard is trusted than when a warehouse of unused plots exists.
Also pin one numeric memory from this vectors and similarity chapter: cos(a,b)=(a·b)/(||a|| ||b||)=(1×2+2×4)/(√5×√20)=10/10=1 That number is not decoration; it is a template for how claims about vectors and similarity on the internal FAQ semantic search should look in design docs. Scoped specifically to vectors and similarity / internal FAQ semantic search / evaluation.

Common mix-ups
People confuse vectors and similarity with neighboring buzzwords when debugging the internal FAQ semantic search. Before changing prompts, ask whether the broken stage was evidence gathering, the vectors and similarity judgment itself, validation, or the product action. Fixing the wrong stage creates folklore (“we tried vectors and similarity and it failed”) that blocks the next team on the internal FAQ semantic search. Scoped specifically to vectors and similarity / internal FAQ semantic search / evaluation.

Rehearsal (vectors-and-similarity/evaluation)
Write a five-line artifact for this page: goal, inputs, check, owner, stop rule. Invent one fluent failure that the check would catch. Keep details specific to vectors and similarity rather than generic AI advice.

Why this matters
A demo of the internal FAQ semantic search looks great on three hand-picked examples of vectors and similarity. What does that demo refuse to tell you?
