Literature Search

Search smarter, not harder

Two weeks of librarian time, compressed to an afternoon. mapped runs your search across 10+ databases simultaneously, deduplicates results automatically, and produces PRISMA-compliant documentation as a side-effect — not a separate task.

Updated April 2026

mapped's Literature Search runs a single PICOS-aligned query across 10+ academic databases at once: PubMed, Cochrane Library (CENTRAL), Scopus, Web of Science, Embase, PsycINFO, CINAHL, IEEE Xplore, Google Scholar, and PROSPERO. The Multimodal Extraction Engine generates database-specific syntax, maps MeSH and Emtree terms, expands synonyms, and balances sensitivity with specificity. Results are deduplicated by DOI, title similarity, and author/year combination, then logged in PRISMA 2020 format ready to drop into your manuscript's methods section.

Key Capabilities

Multi-Database Search

Single query, ten parallel runs: PubMed, Cochrane Library (CENTRAL), Scopus, Web of Science, Embase, PsycINFO, CINAHL, IEEE Xplore, Google Scholar, and PROSPERO. No separate accounts, no syntax translation, no manual export-and-merge dance.

AI-Powered Query Generation

mapped generates one optimized search string per database — PubMed gets MeSH, Embase gets Emtree, Scopus gets its own field codes — plus synonym expansion and sensitivity/specificity tuning. You review and modify every query before execution. The AI accelerates; you control the strategy.

MeSH and Emtree Mapping

Controlled-vocabulary mapping is automatic. mapped identifies the right MeSH and Emtree terms, explodes them where appropriate, and combines them with free-text synonyms — the gold-standard pattern librarians use, applied at AI speed.

Automatic Deduplication

Records identical across databases are merged. The deduplication engine matches by DOI first, then title similarity (fuzzy match accounting for capitalization and punctuation), then author/year combination. Near-duplicates are flagged for manual review rather than silently merged.

PRISMA 2020-Compliant Documentation

Every search auto-logs the full search string per database, the date of search, records retrieved before and after deduplication, and any limits applied. The documentation exports straight into your manuscript's methods section and the PRISMA flow diagram — no manual transcription.

Reference-Manager-Ready Export

Results export in RIS (EndNote, Zotero, Mendeley), BibTeX (LaTeX workflows), CSV, or Excel. Whatever your team uses for reference management or downstream analysis, mapped's output drops in unchanged.

Frequently asked questions

What is mapped's Literature Search?
It's a federated search across 10+ academic databases — PubMed, Cochrane CENTRAL, Scopus, Web of Science, Embase, PsycINFO, CINAHL, IEEE Xplore, Google Scholar, and PROSPERO — driven by AI-generated, database-specific queries with automatic deduplication and PRISMA 2020-compliant logging.
Which databases does mapped search?
PubMed, Cochrane Library (CENTRAL), Scopus, Web of Science, Embase, PsycINFO, CINAHL, IEEE Xplore, Google Scholar, and PROSPERO out of the box, with new sources added regularly. You don't need separate accounts — mapped handles the syntax translation per database.
Is the AI-generated query as good as a librarian's?
It's a strong starting point that you should review. mapped maps MeSH and Emtree, expands synonyms, and balances sensitivity with specificity — but a research librarian's judgement on edge cases is still valuable. The AI accelerates the mechanical work; you keep editorial control over the final strategy.
Does mapped handle deduplication automatically?
Yes. Records are matched on DOI, then title similarity (fuzzy match), then author/year combination. Exact duplicates are merged silently; near-duplicates are flagged for manual confirmation. The before/after counts feed straight into the PRISMA flow diagram.
How much does Literature Search cost?
The free tier includes a 5-database search. The Mapped Project tier (list $119/project, currently $79 launch pricing) unlocks all 10+ databases, AI query generation across every database, and full PRISMA logging. Custom Enterprise plans add unlimited projects and SSO. Pricing details at mappedresearch.com/pricing.
Can I export results to Zotero, EndNote, or Mendeley?
Yes. Every search exports in RIS, BibTeX, CSV, or Excel formats — compatible with Zotero, EndNote, Mendeley, RefWorks, and any LaTeX or statistical workflow. Your team can keep using the reference manager you already have.
