Error in attempting to query

[Matthew Castrigno <ca...@slhs.org>]

using
http://nameRemoved:8983/solr/sls/select?indent=true&q.op=OR&q=*%3A*
I get the response:

{
  "responseHeader":{
    "status":400,
    "QTime":0,
    "params":{
      "q":"*:*",
      "indent":"true",
      "q.op":"OR"}},
  "error":{
    "metadata":[
      "error-class","org.apache.solr.common.SolrException",
      "root-error-class","org.apache.solr.common.SolrException"],
    "msg":"Unknown top-level key in JSON request : command",
    "code":400}}

This core has only one document but attempting to delete it in the UI results in the message:

Document is missing mandatory uniqueKey field: doc_id

​I have somehow managed to index a document without the uniqueKey  and now I cannot delete it.
Is there a way to delete this document without using a q parameter?
How can salvage this?

Thank you in advance for any insights.
