Hello,

We are using OpenSearch in DSpace 5.8 to provide dynamic RSS feeds for some
queries. I am wondering if there is any sort of advanced query syntax to
limit the search results similar to what is possible in the Discovery
search with "equals" and "contains".

For example, this Discovery query for "Apple" will only return items where
the subject matches the term "Apple" exactly:

https://dspace/discover?filtertype=subject&filter_relational_operator=equals&filter=Apple

Whereas this OpenSearch query will return items matching "Apple" and any
others that contain the search term like "Apples and Bananas".

https://dspace/open-search/discover?query=subject:Apple&sort_by=3&order=DESC

Thank you,
