Hi, Sini: The term "metadata" may have created an unhelpful expectation.
In the Search API, metadata extraction gets nodes from the content of the result document other than the nodes matched by the query criteria. It's called "metadata" because it's often general information such as the identifier or title. Thus, when extracting metadata, the query options can specify only a XML element or attribute, JSON key, or field (whether directly or indirectly by reference to a constraint). A collection does not appear in the content of a document, so the query options can't extract a collection as metadata. Also, a collection is just a tag associated with one or more documents. A collection has no metadata to extract. Can you expand a bit about the goal here?

I have included the below node in the options. <search:extract-metadata> <search:constraint-value ref="provider"/> </search:extract-metadata> I get the result with all the collection details that exist for the search doc. Thanks, Sini
