Frontier analysis — Recommendation — Knowledge Platform / Search Architecture
Knowledge boundary
- Source: knowledge-platform/search-architecture.md
- Status: active (inferred from publishable inventory)
- Discipline: Engineering
- Confidence: stated in source; mixed
- Primary objective: purposes: - decide - apply - reference audiences: - practitioner - contributor
- Primary claims/evidence: Use hybrid retrieval: - Metadata filters for precision - BM25 or equivalent lexical search for exact terminology - Embedding search for semantic recall - Graph traversal for concept-aware expansion and citation paths
- Methodology: 1. Normalize metadata and chunk canonical summaries plus section-level document chunks. 2. Build a lexical index over full text, titles, headings, IDs, and concept labels. 3. Build a vector index over canonical summaries and semantically chunked sections. 4. Build a graph index over concepts, documents, evidence, and lineage edges. 5. Fuse results with confidence, authority, and recency weighting.
- Limitations/known uncertainties: Not explicitly labeled; the frontier records below treat missing replication, boundary, measurement, transfer, and benchmark evidence as unresolved.

Challenge and confidence decay
The source was challenged for construct validity, independent replication, boundary conditions, transfer, and comparative baselines. Confidence should decay when the source lacks a dated replication, when its technology or target population changes, or when later artifacts report contradictory findings. Revalidation is recommended before treating context-bound recommendations as universal.
