Enterprise Search defined
Common search concepts and terms
Search architecture
SharePoint search technologies
What is Enterprise Search
• Why not use Google Appliance aka “Google Box”?
• Why not use open source engine like Lucene?
• Why SharePoint search isn’t enough?
• Do I need taxonomy & faceted search?
• Can users just go ahead and tag everything?
Enterprise is not just a
large Intranet
• Large volumes of data
• Usually there exists a “right” or highly relevant
document
• Security is critical
• Taxonomies and vocabularies are important
• Dates are important
• Corporate data does have structure
• Search is convenient for surfacing content
• Search is promising for future BI applications
Search Scenarios
• Two types of scenarios in an enterprise:
o Productivity search
• Intranet/team collaboration search
• People search/Social computing
• Site search
o Search applications
• Parts search (fuzzy search requirement)
• Intelligence & Investigation (heavy use of entity extraction)
• IP protection
• Compliance/Records management
• E-commerce
• Knowledge management & Support
• BI applications
