----------------------------------------

             Summary: Using query time Join in deleteByQuery throws ClassCastException
                 Key: SOLR-6357
                 URL: https://issues.apache.org/jira/browse/SOLR-6357
             Project: Solr
          Issue Type: Bug
          Components: query parsers
    Affects Versions: 4.9
            Reporter: Arcadius Ahouansou


Consider the following input document where we have:
- 1 Samsung mobile phone and
- 2 manufactures: Apple and Samsung.

{code}
[
   {
      "id":"galaxy note ii",
      "cat":"product",
      "manu_s":"samsung"
   },
   {
      "id":"samsung",
      "cat":"manufacturer",
      "name":"Samsung Electronics"
   },
   {
      "id":"apple",
      "cat":"manufacturer",
      "name":"Apple Inc"
   }
]
{code}

My objective is to delete from the default index all manufacturers not having any product in the index.

After indexing (  curl 'http://localhost:8983/solr/update?commit=true' -H "Content-Type: text/json" --data-binary @delete-by-join-query.json )

I went to
{code}http://localhost:8983/solr/select?q=cat:manufacturer -{!join from=manu_s to=id}cat:product
{code}

and I could see only Apple, the only manufacturer not having any product in the index.

However, when I use that same query for deletion: 
{code}
http://localhost:8983/solr/update?commit=true&stream.body=<delete><query>cat:manufacturer -{!join from=manu_s to=id}cat:product</query></delete>
{code}

I get
{code}
java.lang.ClassCastException: org.apache.lucene.search.IndexSearcher cannot be cast to org.apache.solr.search.SolrIndexSearcher
	at org.apache.solr.search.JoinQuery.createWeight(JoinQParserPlugin.java:143)

	at org.apache.lucene.search.BooleanQuery$BooleanWeight.<init>(BooleanQuery.java:185)

	at org.apache.lucene.search.IndexSearcher.createNormalizedWeight(IndexSearcher.java:684)
	at org.apache.lucene.search.QueryWrapperFilter.getDocIdSet(QueryWrapperFilter.java:55)
	at org.apache.lucene.index.BufferedUpdatesStream.applyQueryDeletes(BufferedUpdatesStream.java:552)
	at org.apache.lucene.index.BufferedUpdatesStream.applyDeletesAndUpdates(BufferedUpdatesStream.java:287)
	at 
{code}

This seems to be a bug.
