[jira] [Commented] (SOLR-381) delete-by-query does not support
purely negative queries
[ https://issues.apache.org/jira/browse/SOLR-381?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13246498#comment-13246498 ]
David Peterson commented on SOLR-381:
-------------------------------------
The workaround gives a syntax error.
java -Ddata=args -jar /opt/solr/example/exampledocs/post.jar ": -userid:*"
java -jar /opt/solr/example/exampledocs/post.jar *.xml
SimplePostTool: version 1.4
SimplePostTool: POSTing args to http://localhost:8983/solr/update..
SimplePostTool: FATAL: Solr returned an error #400 Error parsing Lucene query SimplePostTool: version 1.4

> Key: SOLR-381
> URL: https://issues.apache.org/jira/browse/SOLR-381
> Project: Solr
> Issue Type: Bug
> Components: update
> Reporter: Erik Hatcher
> Priority: Minor
>
> Reported by Rob Casson:
> indexing the example docs from 1.2, these steps work:
> curl http://localhost:8983/solr/update --data-binary
> '<delete><query>solr</query></delete>' -H 'Content-type:text/xml;
> charset=utf-8'
> curl http://localhost:8983/solr/update --data-binary '<optimize />' -H
> 'Content-type:text/xml; charset=utf-8'
> but if i reindex, and change the delete query to a negative, the
> non-'solr' docs don't get deleted:
> curl http://localhost:8983/solr/update --data-binary
> '<delete><query>-solr</query></delete>' -H 'Content-type:text/xml;
> charset=utf-8'
> curl http://localhost:8983/solr/update --data-binary '<optimize />' -H
> 'Content-type:text/xml; charset=utf-8'
> And detailed by Hoss with a workaround:
> the delete by query does "the
> right thing" with a purely negative query ... when the customization was
> added to Solr to support pure negative queries it was done at the
> SolrIndexSearcher level when computing DocSets, but delete by query uses a
> lower level method passing in a HitCOllector.
> the work arround is to include *:* in yoru query ...
> <delete><query>*:* -solr</query></delete>
> ... if/when this is fixed
> in Solr that's esentally what solr will do under the covers.
