  • 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.)
  • Interacting with Search
    Search Center
    Query String
    RSS
    KeywordQuery Class
    FullTextSqlQuery Class
    Web Service
  • 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
  • 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
  • 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.
  • 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
  • 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
  • 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
  • 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
