In our Sitecore 9.2.0 solution, I want to present data from a microservice to the editors. The editors should be able to browse and select one or more items from the microservice.
My initial idea was to create an index for the content from the microservice and then create a custom field that supports browsing and selecting content from the index.
Unfortunately, I have not found any information on how to create a Sitecore content field, that enables querying/select data from an index (SOLR/Azure). Does anyone have any experience with a scenario like this?
