We need to know a lot more to help you track it down. What query are you running that gives you the error? Do all queries cause that error or only certain ones? Have you tried modifying the query to see if there’s a certain field that causes the error to appear or disappear? How did you convert from Solr 3.6.1 to 8.10.1? Did you do a full reindex of the cores? Have you searched for that error message online? This StackOverflow answer is the first thing that shows up, and summarizes what I expect is the problem: https://stackoverflow.com/questions/17521287/solr-3-5-mutliple-values-encountered-for-non-multivalued-field <https://stackoverflow.com/questions/17521287/solr-3-5-mutliple-values-encountered-for-non-multivalued-field> Andy
