    • 3. What is Enterprise Search?
      Enterprise Search is one of Microsoft’s current offerings to do search in the Enterprise
      Included in MOSS 2007
      Also available as a stand alone product (Search Server 2008 / Search Server Express)
      Allows for indexing and querying of documents from multiple sources (i.e.: documents, web sites, file shares, Active Directory (people), databases, web services, etc.)
    • 4. Interacting with Search
      Search Center
      Query String
      RSS
      KeywordQuery Class
      FullTextSqlQuery Class
      Web Service
    • 5. Keyword Query Syntax
      Used to search by Managed Properties
      Can specify Scopes (Scope:”MyScope”)
      Does not support wildcard search
      AND implied between each keyword (i.e.: Color:”Red” Size:”M” is the same Color=“Red” AND Size=“M”)
      OR implied when multiple keywords of the same managed property used (i.e.: Color:”Red” Color:”Blue” translates to Color=“Red” OR Color=“Blue”)
      Can Specify Content Sources (ContentSource:”My Source”
      IsDocument:”1” – Query Documents Only
    • 6. URL Syntax
      Search Center and RSS pages accept queries via the query string
      Uses the keyword syntax specified on the K parameter (i.e.: results.aspx?k=Accounting)
      Can specify scope using the S parameter (i.e.: results.aspx?k=Account&s=Corporate Documents)
      Results can be paged with the start parameter
    • 7. KeywordQuery Class
      SharePoint API class to execute a query using Keyword Syntax
      Returns a ResultsTableCollection object which can be converted to a DataTable
      Can only be used on the SharePoint server
      Uses the credentials of the application executing the code (i.e.: the user who ran a console application, or the application pool account)
      SelectProperties can be used to add custom managed properties. You must add all default properties as well as your own custom properties if this is used.
    • 8. Full Text SQL Syntax
      T-SQL style method of querying Enterprise Search
      Can be used to do a wildcard search
      Specify columns in SELECT statement
      SELECT Title, Path, Write, Rank,…
      Always FROM Scope()
      Note syntax when using WHERE with a Scope
      WHERE “Scope” = ‘File Share’
      CONTAINS predicate supports wildcard search, FREETEXT does not
      ORDER BY clause can be used for ordering
      See Office Server SDK for more information
    • 9. Web Services
      Located on your SharePoint server in the _vti_bin virtual folder
      /_vti_bin/search.asmx – Enterprise Search web service
      /vti_bin/spsearch.asmx – WSS3 Search web service
      Both use the same syntax
      Web Service requires authentication
      Specify using .Credentials property
      Requires an input XML string
      Query method returns an XML string
      QueryEx method returns a DataSet
    • 10. Query Request Schema
      Can use Keyword Query syntax or Full Text SQL Query syntax
      QueryText element contains the query
      type=“STRING” – Keyword Query
      type=“MSSQLFT” – Full Text SQL Query
      Range / StartAt/ Count elements can be used for paging
      Properties element can be used to specify custom managed properties when using Keyword Query syntax
      SortByProperties element sorts keyword queries
      Note the casing of everything
    • 11. RSS
      Can use the URL syntax with the RSS page at http://<moss-server>/<SearchCenterUrl>/_layouts/srchrss.aspx
      Returns an XML document in RSS format containing search results
      Will not return custom managed properties
