We are applying sorting by title to one of our collections. Reading the funnelback docs, this is standard funnelback feature, and does not need any additional configuration.
We are encountering some issues with sorting by title (alphabetical sorting), looking at the native JSON output (/s/search.json) results do not seem to be sorting when multiple terms are in the query.
When adding sort=title to the url, sorting works when the query contains one term, for example:
When sort is applied when two terms are used in the query, the sort does not work, only listing results in rank order, and not alphabetical order.
