General help

I created a Moodle server on Ubuntu and copied over data from our Windows Moodle test server. Everything is working fine. Installed Moodle 3.4 and PHP 7.0. I have a user that manages the courses and he wanted a global search plugin installed, specifically Solr. I have that installed but everytime I run a search, I receive an error of Invalid Parameter value detected even though it seems to have found items that were searched for. Would someone be able to tell me what parameters I am looking for and in what file? This is only happening on the global search page so I assume that it would be the solrconfig.xml file? I have attached a screenshot of the error. Thanks for your help! Ryan
