Average Solr Server Spec.

[Furkan KAMACI]

This question may not have a generel answer and may be open ended but is
there any commodity server spec. for a usual Solr running machine? I mean
what is the average server spesification for a Solr machine (i.e. Hadoop
running system it is not recommended to have very big storage capably
computers.) I will use Solr for indexing web crawled data.
