We have a problem with searching RssContent with UnifiedSearch.
We need to be able to search on the field SearchAuthors, which is populated when looking at the index records. However when searching with names in that are in the SearchAuthors, it returns 0 hits. Searching with words in the title or content works well.
I don't know if this is relevant, but when looking at the returned UnifiedSearchHit, the Authors field is null, and the authors key in MetaData is filled with the correct value.
