Advanced search queries in DataCite Commons
Searches for Works in DataCite Commons follow the same structure as the query string used in the REST API .
Field names
Queries by default search commonly used fields, but a specific field can be provided in the query, e.g. https://commons.datacite.org?query=publicationYear:2016
For nested fields use the same format as in the REST API response, e.g. https://commons.datacite.org?query=creators.nameIdentifiers.nameIdentifierType:ORCID
Wildcards
Wildcards are supported, e.g. https://commons.datacite.org??query=creators.familyName:mil*
Boolean operators
By default, all terms are optional, as long as one term matches. Use + or - to specify terms that have to match or not match, respectively. For example https://commons.datacite.org?query=titles.title:climate%20+change
Ranges
For number and date fields, we can specify a range. Wildcards are supported e.g. https://commons.datacite.org?query=publicationYear:[2019%20TO%20*] or https://commons.datacite.org?query=view_count:[1000%20TO%201999]
It is possible to search any element from the DataCite metadata schema using the JSON API response format for the query, for example to search the title:
titles.title:Mars
Run this search in DataCite Commons.
The syntax you use for the query must match the elements in the JSON API (different to the XML). All the properties are listed in API the response below. More examples are listed in the examples section.

Examples
1. Search for a specific publisher
publisher:DataCite
Run the publisher example search in DataCite Commons.
2. Search for a single DOI
To search for a specific DOI use the DOI field in the metadata.
doi:10.11570/18.0006
Run the example DOI search in DataCite Commons.
3. Search the affiliation
In this case include both the parent and child elements from the schema and use a period (.) to separate the different levels in your search query.

"creators": [
{
"name": "Bloggs, Jane",
"nameType": "Personal",
"givenName": "Jane",
"familyName": "Bloggs",
"affiliation": "DataCite",
"nameIdentifiers": [
{
creators.affiliation.name:DataCite
Run the example affiliation search in DataCite Commons.
4. Use quotes
To search for an exact string, for example, an authorâs name, include the text between quotation marks, the search looks for the the exact string contained within the quotes.
titles.title:"CrowdoMeter Tweets"
Run the example search using quotation marks in DataCite Commons.
5. Using operators ( e.g AND OR + -)
Building more complex queries can be done with different syntax including AND OR + - (AND / OR must be capitalised)
Search for all works using the AND operator.
types.resourceTypeGeneral:Software AND types.resourceType:XML
Run the example query using the AND boolean in DataCite Commons.
Search for works using the "AND" and "OR" booleans.
publisher:DataCite AND types.resourceTypeGeneral:(Text OR Dataset)
Run the example query using the AND / OR booleans in DataCite Commons.
6. Wildcards
To run a broader search you can include the wildcard (*)
Search for all works with the subject robot*
subjects.subject:robot*
Run the example query using the wildcard in DataCite Commons
7. Longer queries
Combine numerous elements to limit the search results. In this example the creators and the relatedIdentifier properties are used to build the query:
creators:
"creators": [
{
"name": "Fenner, Martin",
"nameType": "Personal",
"givenName": "Martin",
"familyName": "Fenner",
"affiliation": [],
"nameIdentifiers": [
{
"nameIdentifier": "https://orcid.org/0000-0003-1419-2405",
"nameIdentifierScheme": "ORCID"
}
]
}
],
relatedIdentifiers:
"relatedIdentifiers": [
{
"relationType": "HasPart",
"relatedIdentifier": "10.5438/6423",
"relatedIdentifierType": "DOI"
},
creators.name:"Fenner, Martin" AND relatedIdentifiers.relationType:hasPart
Run this longer query example combining 2 elements in DataCite Commons.
