[Koha-devel] Return to search results?

I'm working on the opac-detail template, and thinking about keeping the patron oriented in the search process. Our current system (Spydus) provides a link from the detail view back to the search results view. I think Spydus uses some kind of session-tracking to do this. Is there a good way to provide this functionality in Koha? Maybe the simplest way would be to pass the query terms back and forth in the URL? Or is there a better alternative? -- Owen
