The ORCID search API uses the SOLR syntax. All query syntaxes available in SOLR 3.6 are supported, including Lucene with Solr extensions (default), DisMax, and Extended Dismax.
You can use a fielded search when you need to search a specific section of the ORCID record. The current list of fields recognized in the API search, along with their corresponding record structure elements, are as follows:

*Although Ringgold identifiers still exist within the ORCID registry, as of 1 August 2023, ORCID no longer receives updates to the RINGGOLD organization identifier database used by our Registry, nor will we be able to process or use RINGGOLD IDs created after that date. See our FAQ for more info
