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:
