What is Semantic search?

Vector or embedding search that ranks by meaning rather than keywords. Jobs: similar-document find; embedding retrieval apis; hybrid keyword-plus-vector ranking.

What problems does it solve?

Keyword retrieval misses paraphrases in large unstructured collections.

Typical business use cases

  • Similar-document find
  • Embedding retrieval APIs
  • Hybrid keyword-plus-vector ranking

Important capabilities

  • Embeddings
  • ANN index
  • Hybrid ranking

What buyers should evaluate

  • Domain fit of embeddings
  • Index ops
  • Whether generation is bolted on

Risks and governance considerations

Semantic neighbours that leak across permission boundaries.

Procurement checklist

  • Embedding model identity
  • ACL on vectors
  • Rebuild process

Relevant AI Trustmark assurance

AI Trustmark independent findings appear only when an assessment or certificate exists. Category membership does not imply verification.

Frequently asked questions

What is Semantic search?

Vector or embedding search that ranks by meaning rather than keywords. Jobs: similar-document find; embedding retrieval apis; hybrid keyword-plus-vector ranking.

What should not be listed as Semantic search?

Products whose buyer job is full enterprise search suites, knowledge graphs, or RAG generators. Those belong on their own category page so search queries are not split.

Has AI Trustmark independently assessed every Semantic search supplier?

No. A category listing is descriptive. Independent assessment is shown only on company or product pages that carry Trustmark evidence.

What should buyers ask about AI data retention and deletion?

Establish how long prompts, files, traces and embeddings are kept, who can access them, and how deletion is evidenced. Retention in a debug or eval store can outlast the customer contract if it is not in scope.

What model or provider changes should a buyer insist on being told about?

Material change usually includes a new model family, new region, new subprocessor, new write-capable tool, or a change that affects logging, privacy or human oversight. Those changes should trigger evidence refresh rather than a silent release.

How should buyers verify where AI customer data is processed?

Ask for the named processing locations, cloud regions and any subprocessors that see prompts, files or outputs. A directory listing is not evidence of residency. Independent assessment records the locations that were in scope on the assessment date.

Does a TrustMark on one product cover the rest of the company?

No. Independent assessment is scoped to the named organisation and, where relevant, the named product. Category pages list suppliers as a topic label. They do not imply that every listed company has been assessed.

What incident-handling evidence is useful for AI suppliers?

Buyers should see how AI-specific failures are detected, contained and notified — including unsafe outputs, data leakage and unauthorised agent actions. An incident policy that never mentions models, prompts or tools is incomplete for this class of product.
