Possible? Secondary Sort By in URL?

I managed to make the results of a URL-defined search sort alphabetically by author by adding "+order+by+authors" to the URL, but I can't be sure what the default secondary sort is. Is there a way to define the secondary in the URL so that one can, for example, have search results sorted by author and then by year (when there is more than a single record authored by a given person)?

Thanks,
Ben

Multi-level sorting is

Multi-level sorting is supported in the references module. Please go to "Tools | Customize...". Go to the "Commands" tab and "References" category. You can then bring the "Sorting..." command to the menu or toolbar. Paul

Re: Possible? Secondary Sort By in URL?

I'm sorry, I meant in BiblioWeb. The URLs I modified were built to bring guest BiblioWeb users to certain search results, which I wanted sorted by author and then by year. I managed to have the results sorted by author, so I'm wondering if it's possible to define the 2nd sort criterion for when there is more than a single record authored by a given person.

Ben, you can edit the URL

Ben, you can edit the URL and make it look like: ...order+by+author,+year_pub...
