I am looking for a professional search server system with functionality, like e.g. solr http://lucene.apache.org/solr/ holds.
Place of action should be a centralized location, whereon many hosts would request data.
Furthermore the system should be extensible for implementing statistical procedures. (e.g. a kind of heatmap (or common diagrams) of a (or more) file(s) (which has a guid), that is spread on different hosts.)
This software doesn't have to be opensource.
