Evidence discovery
A traceable retrieval layer for systematic reviews
Use repeatable queries, bibliographic filters, and source identifiers to support discovery and screening without hiding the evidence trail.
A practical retrieval workflow
01
Define a stable query set
Record each information need, synonym, date range, and inclusion criterion before retrieval.
02
Retrieve candidates
Search scholarly records and use available type, publication-date, ISSN, and URI filters to narrow the pool.
03
Screen with evidence
Review metadata, abstracts, matched passages, and available full text while preserving exclusion reasons outside the search system.
04
Export the audit trail
Store the exact query, timestamp, filters, rank, and canonical identifiers so the discovery phase can be repeated.
What the retrieval layer returns
- Ranked scholarly candidates with bibliographic metadata.
- Matched passages that help prioritize manual screening.
- Available abstracts, full text, and reference lists.
- Stable identifiers for deduplication and review records.
Important boundaries
- Space Frontiers is not a complete registry of every published or unpublished study.
- Ranking is not an inclusion or quality judgment.
- A formal review should search multiple databases and document all sources.
- Clinical or policy decisions require domain experts and established review protocols.
Implementation paths
Start with the interface that matches your prototype. The source identifiers and document model stay consistent as you move from manual exploration to an agent or application.
