There's not enough information here to answer the question Alexandre needed answered -- did you reindex *everything* in the core with the changed schema.xml file? I recommend deleting the index directory entirely before reloading the core. You might wonder why this is necessary. Here's why: When you change your schema, nothing happens to the existing data in the index. When Solr tries to access that data, it uses the schema as a guide to interpreting that data. If the index contains rows that have a field built with a SortableIntField definition and then Solr tries to access that data with a different definition (such as TrieIntField), there's a good chance that an unrecoverable error will occur, because the formats are very different on the disk. https://wiki.apache.org/solr/HowToReindex Thanks, Shawn
