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

This seems to be a bug.
