UI: generic Server Error when searching for * or + (asterisk or plus)

Nomad version

2.0.0

Operating system and Environment details

Debian 13.6, 3 node server cluster, multiple clients

Issue

When entering * or + in the search field on the /ui/jobs page, there is a Server Error page.

Reproduction steps

1. Open the web UI
2. Enter * or + in the search field

Expected Result

Either the search should return nothing or convert it to a valid regex. The current behaviour is confusing as it sends the user to an error page instead of stating what the problem is.

Actual Result

Server Error
