Hoss Man updated SOLR-3432:
---------------------------
Description:
deleteByQuery is silently ignored if there the updateLog is configurd in
solrconfig.xml, but there is no {{\_version\_}} field in the schema.xml (ie: if
someone copies the example configs, and then prunes down the schema to remove
fields they don't think they need/want)
To reproduce:
* comment out {{\_version\_}} in example schema
* {{java -jar start.jar}}
* {{java -Ddata=args -jar post.jar '<add><doc><field
name="id">HOSS</field></doc></add>'}}
* {{java -Ddata=args -jar post.jar '<delete><query>id:HOSS</query></delete>'}}
** or: {{java -Ddata=args -jar post.jar
'<delete><query>\*:\*</query></delete>'}}
Note in the logs that SolrCore logs the deleteByQuery, but there is no log of
it executing...

Summary: deleteByQuery silently ignored if updateLog is enabled, but
{{_version_}} field does not exist in schema (was: deleteByQuery silently
ignored unless {{_version_}} field exists in schema )
If the underlying problem is that updateLog is useless w/o a {{\_version\_}}
field, then it should probably be a hard startup failure if updateLog is
enabled w/o {{\_version\_}} existing.
Alternatively: given some of the problems we've seen (and will likley continue
to see) with users not realizing when {{\_version\_}} is mandatory (ie:
upgrading from simple solr to SolrCloud) we might consider adding to the
IndexSchema automagically on startup if it isn't explicitly declared in
schema.xml
