: We haven't changed Solr versions. We've been using 3.1.0 all along. but that's not what i'm talking about. I'm talking about the "schema version" ... a specific property declared in your schema.xml file.
did you check it? (even when people start with Solr X, they sometimes are using schema.xml files provided by external packages -- Drupal, wordpress, etc... -- and don't notice that those are from older versions) : Plus, I have some code that runs during indexing and retrieves the : fields from a SolrInputDocument, rather than a SolrDocument. That code : gets Strings without any problem, and always has, even without saying : multiValued="false". SolrInputDocument's are irelevant. they are used to index data, but they don't know anything about the schema. A SolrInputDocument might be completely invalid because of multiple values for singled value fields, or missing values for required fields, etc... what comes back from a search *is* consistent with the schema (even when there is only one value stored in a multiValued field) -Hoss
