query.SelectProperties.Add(“Customer”);
query.QueryText = “Author:Erik SharePoint”;
ResultTableCollection results = query.Execute();
Search API
• FullTextSqlQuery
– Allows highly customized MSFT Full text search
syntax queries
– Namespace: Microsoft.Office.Server.Search.Query

SSP ADMINISTRATION
SSP Administration Overview
• Search is managed at the Shared Service
Provider (SSP)
• Provides management of:
– Content Sources (What is being indexed)
– Managed Properties (How users want to perform
advanced searches)
– Scopes (How users want to search)
– Relevance (What content sources are more relevant)
– Health (What are users searching for and how are my
crawls performing)
Content Source Management
• What can we index?
–
–
–
–
–
–
SharePoint Sites (v2, v3)
Web Sites
File Shares
Exchange Public Folders
Lotus Notes
Business Data (BDC)
Business Data Catalog
• MOSS 2007 (e-cal) provides access to business
data to users
– Data is accessed through the Business Data
Catalog
•
•
Databases
Web Services
– Exposed to many features in SharePoint
•
•
Web Parts (Lists and Details)
Metadata Columns
Business Data Catalog
• Search can easily index the data
– No need to write code
– Highly customizable results
– Launching pad into other web-based, querystringaddressable applications.
– Integrated search results in the search center:
•
•
•
Documents
Web Content
Business Data
Metadata Property Mappings
• Crawled Properties
– SharePoint “discovers” properties during crawl
– Organized in categories
– Can be included/excluded in the index
• Managed Properties
– Out-of-the-box Managed Properties
– Custom-defined Properties (i.e. CustomerName)
• CustomerName:Acme
– One Managed Property can be associated to 1 or
more Crawled Properties
Scope Management
• Logical organization of crawled content
• Rule-based
– Web Address / Folder
– Property Query (Author = John Doe)
– Specific Content Source
• Supports multiple rules (joined via ANDs / Ors)
• Supports content exclusion
• Site Collections “opt-in” to SSP-defined scopes
Relevancy
• Authoritative Pages
– Three levels of “authority”
– Ability to demote sites
• Relevancy API
– API Available to change the ranking of managed
properties
Crawl Log
• Administrative interface for viewing crawl history
• Summary View
• Details View
Search Usage Reporting
• Out of the box usage reporting
in MOSS
– Query volume trends, top queries,
click through rates, queries with zero
results, etc.
– At both SSP and site collection levels
– Export data for extended reporting in Excel

• Define Display Groups
• Groups Control Visibility on Search Web Parts
Search Visibility
• Control if a site shows up in search results
• Sites are already security trimmed
• Example: Search Center Set to “No”
Keywords & Best Bets
• Use query reporting
to help define
keywords
• Use keywords to
provide access to
content inaccessible
to the crawler
