Sorting

Sorting is controlled by the sortBy parameter, in the format fieldname sortDirection, where sortDirection is ASC (ascending) or DESC (descending).

Research products can be sorted by:

• relevance (default)
• publicationDate
• dateOfCollection
• influence
• popularity
• citationCount
• impulse

The default sorting is relevance DESC.

Examples:

• Get research products published after 2020-01-01, sorted by publication date descending:

  /v3/research-products?fromPublicationDate=2020-01-01&sortBy=publicationDate DESC

You can combine multiple sort conditions by separating them with a comma:

• Sort by publication date ascending, then by popularity descending:

  /v3/research-products?search=COVID-19&sortBy=publicationDate ASC,popularity DESC
