Biomedical and life-sciences literature.
A broader evidence base from one supplementary search
Search multiple academic databases and grey literature at once.
Search seven supplementary sources spanning scholarly databases, preprints, open repositories, and official government publications. Lumina combines and labels the results, removes duplicates, and moves them into one screening workspace.

Step 1
Combine records
Bring results from all selected sources into one list.
Step 2
Remove duplicates
Match repeated citations using DOI and normalized title data.
Step 3
Check metadata
Use Crossref to complete available DOI and citation fields.
Ready to search the live databases?
Create a Lumina workspace, search all seven sources, and move selected scholarly and government records directly into screening.
Designed to complement Scopus
Keep the search you trust. Add seven more discovery routes.
Researchers often rely on established databases such as Scopus. Lumina does not ask you to abandon that method. It adds sources with different disciplinary and open-research coverage, plus official reports and policy evidence that may never appear in journal indexes.
For formal systematic reviews, always validate the search syntax and document the strategy used for each source.

Which scholarly and government sources does Lumina search?
The search spans biomedical, multidisciplinary, preprint, open-research, and official government publication sources.
OA
OpenAlex
Multidisciplinary scholarly works and relationships.
AX
arXiv
Preprints across technical and quantitative fields.
EP
Europe PMC
Life-sciences publications and open research records.
BR
bioRxiv/medRxiv
Recent biology and health-sciences preprints.

OpenAIRE
Open-science, repository, funding, and EU research records.
GP
Government publications
Grey literatureOfficial national and European portals (CELLAR & GOV.UK) with multilingual query expansion across English, Dutch, German, French, and Spanish (not necessarily peer-reviewed).
Crossref metadata checking
After retrieval, Lumina uses Crossref records to verify DOIs and complete citation fields when that metadata is available. Source records can still contain gaps, so Lumina does not claim that every field can always be completed.
From search to screening
Spend less time moving records between tools
A single workflow handles the repetitive steps between supplementary discovery and the first screening decision.
Run one supplementary query
Choose the sources and search them in parallel instead of opening separate database and government portals.
Build a cleaner citation set
Combine records, match duplicates, and fill available citation metadata before screening.
Continue in the same workspace
Import selected papers and continue into AI-assisted, traceable title and abstract screening.

Frequently asked questions
Can I search scholarly databases and government publications at once?
Yes. Lumina can run one search across PubMed, OpenAlex, arXiv, Europe PMC, bioRxiv/medRxiv, OpenAIRE, and a bundled Government publications source, then combine the returned records in one workspace.
How does multilingual government search work?
Lumina creates equivalent government-search queries in English, Dutch, German, French, and Spanish. You can review and edit those variants before searching. Retrieved government records retain their official source and are marked as grey literature, not as peer-reviewed research.
Does Lumina replace Scopus?
No. Lumina is designed as a supplementary discovery layer alongside established sources such as Scopus. For a formal systematic review, choose databases appropriate to the research question and document each search strategy.
Can I use the same Boolean query in every database?
Lumina supports simple terms and common Boolean operators. Database syntax and indexing differ, so researchers conducting reproducible reviews should validate how their query is interpreted by each selected source.
How does Crossref metadata enrichment work?
Lumina compares retrieved citations with available Crossref metadata to verify DOIs and complete fields such as authors, journal details, and publication information when those fields are available.
How are duplicate papers handled?
Lumina compares normalized DOI and title data so repeated records from different sources can be merged before they enter the screening workflow.
