Subject [jira] [Created] (SOLR-4040) SolrCloud deleteByQuery requires multiple commits

Darin Plutchok created SOLR-4040:
------------------------------------

             Summary: SolrCloud deleteByQuery requires multiple commits
                 Key: SOLR-4040
                 URL: https://issues.apache.org/jira/browse/SOLR-4040
             Project: Solr
          Issue Type: Bug
          Components: update
    Affects Versions: 4.0
         Environment: OSX
            Reporter: Darin Plutchok
             Fix For: 4.0


I am using embedded zookeeper and my cloud layout is show below (all actions are done on the
"patents' collection only).

First commit/delete works for a single shard only, dropping query results by about a third.
Second commit/delete drops query results to zero.

http://127.0.0.1:8893/solr/patents/update?commit=true&stream.body=<delete><query>dogs</query></delete>
http://localhost:8893/solr/patents/select?q=dogs&rows=0 (results drop by a third)
http://127.0.0.1:8893/solr/patents/update?commit=true&stream.body=<delete><query>dogs</query></delete>
http://localhost:8893/solr/patents/select?q=dogs&rows=0 (results drop to zero)

Note that a delete without a commit followed by a commit drops query results to zero, as it
should:

http://127.0.0.1:8893/solr/patents/update/?stream.body=<delete><query>dogs</query></delete>
http://localhost:8893/solr/patents/select?q=dogs&rows=0 (full count as no commit yet)
http://127.0.0.1:8893/solr/patents/update/?commit=true
http://localhost:8893/solr/patents/select?q=dogs&rows=0   (results drop to zero)

One workaround (produces zero hits in one shot):

http://127.0.0.1:8893/solr/patents/update?commit=true&stream.body=<outer><delete><query>sun</query></delete><commit/></outer>

The workaround I am using for now (produces zero hits in one shot):

http://127.0.0.1:8893/solr/patents/update?stream.body=<outer><delete><query>knee</query></delete><commit/><commit/></outer>
