[jira] [Commented] (SOLR-2618) Indexing and search on more then one type (Mapping)

    [ https://issues.apache.org/jira/browse/SOLR-2618?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13055041#comment-13055041 ] 

Jan Høydahl commented on SOLR-2618:
-----------------------------------

You might want to talk to Chris Male who held a talk about improving SolrJ for interacting with domain objects at Berlin Buzzwords: http://berlinbuzzwords.de/sites/berlinbuzzwords.de/files/IntegratingSolrJEEApplications.pdf

I think your idea about storing a class name with the document and using reflection to pick the right domain object is interesting..

> It would be very beneficial for a project that I am currently working on to have the ability to index and search on various subclasses of an object and map the objects directly to the actual domain-object. This functionality exist in Hibernate search for instance. Is this something that future releases have in mind? I would think that this is something that will make the value of Solr more efficient to a lot of users. 
> We are testing SolrJ 3.2 with the use of the SolrJ client and the web interface to index change and search. It should be possible to make a solution that map against a special type field(like <field name="classtype" type="class">) in schemas.xml that are indexed every time and use reflection against the actual class?
