Description

Search for entries within a specific domain (database). Returns search results with hit count, entries, and available facets for filtering.

Parameters (9)

domain (string, path, required)

The domain to search. Use 'allebi' for all databases, or specific domains like 'uniprot', 'ensembl', 'chembl-molecule', 'pdbe', 'rnacentral', 'europepmc', etc.

Constraints: {'enum': ['allebi', 'uniprot', 'uniref', 'uniref100', 'uniref90', 'uniref50', 'uniparc', 'ensembl', 'ensembl_gene', 'ensemblGenomes', 'ensemblGenomes_gene', 'dgva', 'ega', 'hgnc', 'embl', 'emblstandard', 'sra', 'sra-study', 'sra-sample', 'sra-run', 'sra-experiment', 'coding', 'coding_std', 'gwas_catalog', 'rfam', 'rnacentral', 'rnacentral-litscan', 'alphafold', 'emdb', 'pdbe', 'pdbekb', 'chebi', 'chembl', 'chembl-assay', 'chembl-molecule', 'chembl-target', 'chembl-document', 'metabolights', 'atlas-experiments', 'atlas-genes', 'atlas-genes-differential', 'biostudies-arrayexpress', 'geo', 'omim', 'varsite', 'complex-portal', 'intact', 'intact-interactions', 'opentargets', 'reactome', 'biomodels', 'interpro7', 'interpro7_domain', 'interpro7_family', 'pfam', 'pfam_entries', 'treefam', 'merops', 'pride', 'jpost', 'peptide_atlas', 'massive', 'intenz', 'europepmc', 'biostudies-literature', 'patentFamilies', 'biosamples', 'cellosaurus', 'efo', 'go', 'mesh', 'ols', 'taxonomy', 'biotools', 'ebiweb', 'cancer_models', 'empiar', 'bioimages', 'biostudies-other']}

facetcount (integer, query, optional)

Number of facet values to return per facet (enables faceted search)

Constraints: {'minimum': 1}

fields (string, query, optional)

Comma-separated list of fields to return for each entry. If not specified, only basic fields (id, acc, source) are returned. Available fields vary by domain.

format (string, query, optional, default: xml)

Response format

Constraints: {'enum': ['xml', 'json', 'csv', 'tsv', 'idlist', 'acclist']}

query (string, query, required)

Search query using Apache Lucene syntax. Supports field-specific searches (e.g., 'id:BRCA1_HUMAN'), boolean operators (AND, OR, NOT), wildcards (*, ?), and phrase searches with quotes.

size (integer, query, optional, default: 15)

Number of results to return per page (default: 15, max: 100)

Constraints: {'minimum': 1, 'maximum': 100}

sort (string, query, optional)

Sort order

Constraints: {'enum': ['asc', 'desc']}

sortfield (string, query, optional)
