>From the ref guide: "Field names should consist of alphanumeric or underscore characters only and not start with a digit."
While field naming isn't strictly enforced, having field names like week_-1 is also not guaranteed to be supported. You should change your field name. I raised SOLR-11819 for one place I see in the ref guide where a hyphen is used, if you see any others please add the location to the JIRA (SOLR-11819).
