you haven't given us any information we can use to help you... schema? high level error that wrapped that NFE? full stack trace of the entire error? data you are indexing? https://wiki.apache.org/solr/UsingMailingLists Best guesses: * you aren't indexing into the field you think you are * there is a copyField from teh field you are using into another field you forgot about * you are using an update processor that expects numbers * you are using a DataImportHandler feature that expects numbers -Hoss
