How can I query Zenodo's related identifiers fields?

The Zenodo open data repository offers a web-based query interface with a sophisticated query language. However, I can't get queries for related identifiers (e.g. a data set that supplements a GiHub repository) to return anything.

For example, for this Unix history repository Zenodo data set, the queries for the corresponding GitHub repository (related_identifiers.identifier:"https://github.com/dspinellis/unix-history-repo") and the DOI of the publication that documents it (related_identifiers.identifier:"10.1007/s10664-016-9445-5") return no results. Even simpler queries, such as for data sets whose related identifiers is a DOI (related_identifiers.scheme:doi) or for data sets associated with a supplement relationship (related_identifiers.relation:isSupplementTo) fail to return any results. Other queries, such as for data sets with restricted access rights (accessrights:restricted) or those by a specific creator (creators.orcid:0000-0003-4231-1897) work fine.

It seems that this is a limitation of the current query interface. The query language does not support queries for nested fields, such as the related identifiers. The provided documentation was misleading and has been corrected through this pull request. In addition, a Zenodo developer commented that the corresponding identifiers can be accessed through the related.identifier keyword, for example related.identifier:"10.1109/TSE.2019.2892149".
