Hello All,

I am using 4.0 Alpha and running into an issue with indexing using
HttpSolrServer (SolrJ).

Relevant java code:
            HttpSolrServer solrServer = new HttpSolrServer(MY_SERVER);
            solrServer.setRequestWriter(new BinaryRequestWriter());

Relevant Solrconfig.xml content:

  <requestHandler name="/update" class="solr.UpdateRequestHandler"  />

  <requestHandler name="/update/javabin"
class="solr.BinaryUpdateRequestHandler" />

Indexing documents works perfectly fine (using addBeans()), however, when
trying to do deletes I am seeing issues. I tried to do
a solrServer.deleteByQuery("*:*") followed by a commit and optimize, and
nothing is deleted.

The response from delete request is a "success", and even in the solr logs
I see the following:

INFO: [coupon] webapp=/solr path=/update/javabin
params={wt=javabin&version=2} {deleteByQuery=*:*} 0 1
Jul 18, 2012 11:15:34 AM org.apache.solr.update.DirectUpdateHandler2 commit
INFO: start
commit{flags=0,version=0,optimize=true,openSearcher=true,waitSearcher=false,expungeDeletes=false,softCommit=false}


I tried removing the binaryRequestWriter and have the request send out in
default format, and I get the following error.

SEVERE: org.apache.solr.common.SolrException: Unsupported ContentType:
application/octet-stream  Not in: [application/xml, text/csv, text/json,
application/csv, application/javabin, text/xml, application/json]

I thought that an optimize does the same thing as expungeDeletes, but in
the log I see expungeDeletes=false. Is there a way to force that using
SolrJ?

Thanks in advance,
Briggs
