Assuming you're talking about javascript in the browser, this design
should be avoided.  It requires direct access to Solr from the user's

If that access is granted, and an intelligent proxy is not used in front
of Solr that can detect and deny any attempt to change the index or
access the admin UI, the end user (presumably the entire Internet) will
be able to delete or change the index.  Even if an intelligent proxy is
used, the user might be able to construct denial of service queries that
will make the Solr server incapable of serving legitimate traffic.

It is always better to keep Solr firewalled from user access and query
it from within a web application that only runs on the webserver.

If access to this application (and the Solr server) will be restricted
by a firewall to only a small group of users that can be trusted, then
this design might be OK.
