how do I a delete with a query and filter in solr 4 (w/ solarium)

Question

I'm using Solarium with Solr 4 and I need to delete with multiple criteria. The docs show how to delete with a query

$client = new Solarium\Client($config);

$update = $client->createUpdate();

$update->addDeleteQuery('type:comment');
$update->addCommit();

$result = $client->update($update);

This works fine. But if I need a different criteria, eg writer_id:123, I'm not sure what to do. If I add another addDeleteQuery line the final raw query looks like:

<update>

  <delete>
    <query>type:comment</query>
  </delete>

  <delete>
    <query>writer_id:123</query>
  </delete>

  <commit/>

</update>

It seems this will delete them independently. I'm not sure if it matters but the defaultOperator from the schema is AND. Looks like from http://www.solarium-project.org/forums/topic/change-operator/ that it's not easily overridable yet. I'm not sure how to apply the solution there to delete, if that would work even work here.

How can I delete items in solr using multiple criteria?

Answer 1

Try Clubbing it into a single query <delete><query>type:comment AND writer_id:123</query></delete>

Answer 2

Note update your solrconfig.xml file to allow document deletion via Solr Query, by setting the enableStreamBody to true in your requestParsers configuration under requestDispatchers with the following

<requestParsers enableRemoteStreaming="true"
                    **enableStreamBody="true"**
                    multipartUploadLimitInKB="2048000"
                    formdataUploadLimitInKB="2048"
                    addHttpRequestToContext="false"/>
