Better support multiple search roots on the same page

To better support multiple search roots on the same page it would be good to be able to prefix attributes added to the URL with a configurable prefix. This would allow multiple search roots to modify the url and track their state on page load without interfering with each other.

Currently only one search root on the page can use url attributes, multiple search roots can be on the page if they are all configured to not update the page url.

There are no immediate plans to work on this issue. If you are interested in this feature or would like work on this please comment.
