Problem

• Central site gathering and search response will not scale

Research Question

• Can a distributed architecture be developed that will allow queries to be processed in parallel on multiple platforms at scale?

Strategy

• Develop Search Server architecture and implementation
• Use off-the-shelf software (e.g., Harvest) for local search (HTTPD space)
• Develop Domain Content Descriptor (DCD) that is exchanged among SSs
• Develop Query Content Descriptor (QCD) that maps query against Global Content Descriptor (GCD)
• Route query to other SSs for local search and forwarding
• Roll-up & present results to user
