For some reason, regardless of the search query entered, Omeka S keeps returning the same set of items for the Browse Preview block. Is it something to do with the metadata at the item level?
What kinds of queries are you entering? The “query” field for browse preview wants to be given the “query string” part of a browse page (so, the part after the question mark in the URL you get from performing an advanced search on the item browse page).
I’m entering the kind of query you described. But even if the search parameters change, the results in browse preview don’t.
Same thing is happening to me right now.
