anchor.diff:  If there are parameters available in the custom handler, you can define them in the same way as any other request handler definition.
   
   NOTE: Blob store can only be used to dynamically load components configured in `solrconfig.xml`. Components specified in `schema.xml` cannot be loaded from blob store.

  +== Deleting Blobs
  +
  +Once loaded to the blob store, blobs are handled very similarly to usual indexed documents in Solr.
  +To delete blobs, you can use the same approaches used to delete individual documents from the index,
  +namely Delete By ID and Delete By Query.
  +
  +For example, to delete a blob with the id `test/1`, you would issue a command like this:
  +
  +[source,text]
  +curl -H 'Content-Type: application/json' -d '{"delete": {"id": "test/1"}}' http://localhost:8983/solr/.system/update?commit=true
  +
  +Be sure to tell Solr to perform a <<updatehandlers-in-solrconfig.adoc#commits,commit>> as part of the request
  + (`commit=true` in the above example) to see the change immediately.
  +If you do not instruct Solr to perform a commit, Solr will use the `.system` collection autoCommit settings,
  +which may not be the expected behavior.
  +
  +You can also use the delete by query syntax, as so:
  +
  +[source,text]
  +curl -H 'Content-Type: application/json' -d '{"delete": {"query": "id:test/1"}}' http://localhost:8983/solr/.system/update?commit=true
  +
  +For more on deleting documents generally, see the section <<uploading-data-with-index-handlers.adoc#sending-json-update-commands,Sending JSON Update Commands>>.

  A GET request will return the list of blobs and other details:
  
  
negative.code: 
  The Blob Store REST API provides REST methods to store, retrieve or list files in a Lucene index.
  
  It can be used to upload a jar file which contains standard Solr components such as RequestHandlers, SearchComponents,
  or other custom code you have written for Solr. Schema components _do not_ yet support the Blob Store.
  
  When using the blob store, note that the API does not delete or overwrite a previous object if a new one is uploaded with the same name.
  It always adds a new version of the blob to the index.
  Because the `.system` collection is a standard Solr collection, deleting blobs is the same as deleting documents.
  
  *The blob store is only available when running in SolrCloud mode.* Solr in standalone mode does not support use of a blob store.
