Subject [jira] [Updated] (SOLR-3432) deleteByQuery silently ignored unless {{_version_}} field exists in schema
Date Fri, 04 May 2012 01:40:48 GMT

     [ https://issues.apache.org/jira/browse/SOLR-3432?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Hoss Man updated SOLR-3432:
---------------------------

    Attachment: SOLR-3432.test.patch

figured out the problem has to do with the updateLog: if you have the updateLog enabled, but
you do not have a _version_ field, you get no warnings or errors -- just silently ignored
deleteByQuery.

attached patch causes the udpateLog to randomly be enabled in DirectoUpdateHandlerTest, so
with this patch, you should see testBasics() fail 50% of the time.
