Use Authority in API Query

[jarmo.s...@uni-hildesheim.de]

Hi all,

I need to construct a complex query for the Rest-API using authority values for the author field.
I know how to use authority as a filter (like f.author=1234567,authority) but is it also possible to use authority values in the query-part of a search request and if so how?

(What I am trying to achieve is this: I need all publications where a given person, identified by his authority-value, is either an author (any publication type) or an editor (all publication types excluding book-chapters).

So something similar to q=(dc.contributor.author :1234567,authority) OR (dc.contributor.editor:1234567,authority NOT dc.type:BookPart)

I am doing this on DSpace CRIS 2023.02

Any help or pointer to relevant documentation would be highly appreciated.

Hi all,

I'll answer my own question, in the end ChatGPT gabe me the decisive hint:

One can use authority-IDs in a query by appending '_authority' to the name of the index like 'query=author_authority:123-456-789-123'

This feature is actually documented pretty well but apparently I did not use the correct search terms in google when trying to find it: https://wiki.lyrasis.org/display/DSArchive/Authority+Control+of+Metadata+Values#AuthorityControlofMetadataValues-Searching
