What’s the field and type definition of submit_date? Could that be the issue?
Also, one thing you could do is separate the nested parsers like this:
q={!boost b=… v=$qq}
qq={!dismax qf=‘….’ v=$term}
Relying on `v` to be the string after the closing curly bracket is sometimes
error-prone, and I tend to explicitly define `v` like this to avoid escaping
and parsing hassles.
(whether you set these in the request handler or as explicit params is up to
you, and keeping everything (but `term`) in the request handler definition
would be the cleanest client request way to go, as you’re doing.
