------------------------------

Stefan Groschupf:

    Thanks to your contribution in katta, but do you think the lucene can 
supply some functions like facet and multi-core in solr.
    We all know the patch use Hadoop rpc connect the slave nodes like katta 
your built.
    
    We want a solution in this problem, and build a cloud protoype with Web APP 
server features. But we didn't need your advertisement in Katta.
    Is there zero value for this patch? cost in Network transmission? we all 
know them. If you select distribute search, all the issues you can not avoid.
    
    so plase give us some valuable suggestions or code, do not promote your 
katta, Despise you so advertisement in Katta.
