    An excellent tech note Gitanjali, thanks!!!  I had heard rumors of something like method 1, but had no idea the exact syntax.


    Just a warning about Method 2: It requires direct, unfettered access to the Solr port.  People could also delete entire collections, etc.  Instead of "id:1234" they could do "*:*".  Sometimes this is exactly what an admin WANTS to do, for direct Solr collection maintenance, etc., I've even used it myself to cleanup cruft.  People should just be aware of it.


    I'd say Method 1 is generally preferred, because it uses the Fusion secured port, and Roles-based security.

    In Method 2 the Fusion 'solr' endpoint is used (one that forwards requests to Solr), so the authorization is still in place, no direct access to Solr port. Also, one restriction here that worth to note - current Fusion implementation does not allow use of 'solr' endpoint with non-Fusion managed collections.
