  1. Customizing and Extending Microsoft Office SharePoint Search Tom Rizzo Director, SharePoint thomriz@microsoft.com

  2. Session Objectives • Session Objectives: • Modify the SharePoint Server search UI • Consume SharePoint Search within external applications • Extend the reach of SharePoint search • Build a custom security trimmer • Learn more about Microsoft Search Server and Federation

  3. Agenda • Customizing the built in user experience • Extending the OOB experience

  4. ActionLinks SearchTabs SearchBox CoreResults Statistics Pagination HighConfidence MatchingKeywordsandBest Bets Search Center

  5. Sources, Scopes and Tabs • All Sites and People tabs provided OOB • Add your own Search Tabs • Tabs can be added for additional scopes • Specific site address • Specific property • Specific content source • Include/Exclude • Consists of a layout page and a results page

  6. Search Web Parts • 9 OOB web parts • Search Box • Core Results • High Confidence • Statistics • Pagination • Action Links • Matching Keywords and Best Bets • Search Summary (Did you mean?) • Advanced Search • 2 New ones for MSS – Federated Results and Top Federated Results • Web part properties such as • Formatting • Turning stemming on/off • Number of results returned • XSL

  7. Thesuarus and Synonyms • Customize Thesaurus and Noise Words • Located in drive:\Program Files\Microsoft Office Servers\12.0\Data\Config • tsxxx.xml and noisexxx.txt where xxx is the language code • Thesaurus supports Replacement or Expansion sets • Substitution weights and stemming are supported

  8. Thesaurus Example • <replacement> • <pat>WinNT</pat> • <sub>Windows Server</sub> • </replacement> • <expansion> • <sub weight="1.0">Office SharePoint Server</sub> • <sub weight="0.6">SharePoint</sub> • <sub weight="0.8">MOSS</sub> • </expansion>

  9. Tuning Results • Best bets • Setup best bets at the site collection level • Simple things you can do for relevance • Authoritative pages • Demoted sites • Exclude specific items • Managed Properties • Add your own • Add them to Advanced Search • Change weighting of properties (via the OM, requires a bit of code)

  10. Customize UI With XSLT • Create a custom look and feel or results layout • Modified through web part properties • Leverage the power of XSLT • Formatting • Logic • Math

  11. Walk through of the XSLT • Parameter Section • Parameters passed by results, web part properties • No Keyword Section • You didn’t enter a keyword • No Results Section • No results were returned • Customize with your own message to help users • Main Body Result Section • Where it all happens • Results Template Section • Matches results in XML • Selected column matching – Title, URL, etc. • Hit Highlighting, Auto definition

  12. demo Customizing the Search UI

  13. Recap of Options • Add/Remove/Change Tabs • Add/Remove OOB Web Parts • Add custom web parts • Tune results • Change Web Part Properties • Change XSL

  14. Agenda • Customizing the built in user experience • Extending the OOB experience

  15. Extending Search • Customizing the Query and Results • Query Object Model • Customizing the Index • Index custom data - Protocol Handlers, IFilters, BDC • Custom Query Time Security Trimmer

  16. Query SyntaxURL Syntax • Use Case • Launching a URL from a custom application • Windows Desktop Search • Save searches • Keywords • results.aspx?k=fish • Scopes • results.aspx?k=fish&s=BDC • Sort/View • results.aspx?v=date • results.aspx?v=relevance • Page • results.aspx?start=21 • Property matching • results.aspx?k=“author:Tom –site:http://tom.com”

  17. Query Object Model • Use query OM • To build custom search UI web parts • To have direct access to query and results properties • To invoke custom queries • 2 types of query syntaxes • Keyword • SQL

  18. Query SyntaxKeyword Syntax • Use Case • Business user • Simple and easy to use • Required and excluded term support • Bike –fitness • SharePoint search -author:”Tom Rizzo” • Filter by any string or integer property • Author:Tom Rizzo • Employees:30 • Implicit “AND” behavior • Consistent property:value syntax across Office, Windows and Live search gallery hinges –brass site:http//supportdeskscope:Products

  19. Query SyntaxSQL Syntax • Use Case • Advanced search solutions • Complex queries • Consistent SQL across enterprise and desktop SELECT URL, Title, Description FROM portal..SCOPE() WHERE FREETEXT(‘gallery hinges’) AND SITE = “http://supportdesk” AND SCOPE = “Products” AND NOT CONTAINS(‘brass’)

  20. Query SyntaxSQL Syntax • Full strength, complete coverage • FREETEXT() • Arbitrary groupings for AND, OR, NOT • CONTAINS() • LIKE • ORDER BY ASC | DESC • Removed in MOSS 2007 • UNION ALL • MATCHES • SELECT * • COALESCE TABLE  

  21. Query Object ModelFeatures • Managed code API • Single request – multiple results • Result Types • Relevant results • High confidence results • Special terms • Definitions • Optional parameters • # of Sentences in Summary • Implicit - AND/OR • Number of results • Ignore noise words • Enable stemming • Language

  22. KeywordQuery Result Table Collection SQLQuery Relevantresults Definitions Execute() QueryEngine Highconfidence OptionalParameters Specialterms Local Query Object Path Input Query OM Output ResultTable:IDataReader Site UI CustomClient

  23. However… • Adding Custom Web Parts • OOB Web Parts use sealed hidden object • You’ll need your own query object to share with other Web Parts • You *can* use URL request parameters we pass between pages

  24. Query Web Service • Use Case • Office Research Pane • Windows Desktop Search • Remote application • ASP.Net 2.0, Win Forms, Java apps • Similar features to query object model • Results in XML or data table formats • http://o12server/_vti_bin/search.asmx

  25. Query Web Service • Methods • Query – returns results as XML format • Research and Reference Service-compatible XML • Used in the Office Research pane • QueryEx – • Returns .NET DataSet • Different result types, features • GetSearchMetaData – Retrieve available properties and scopes • Registration • Status

  26. demo Query Web Service

  27. Refine results using various properties View byrelevance orsocial distance Finding People

  28. Finding People • People Search • Implements the core results • Customizes the search experience • Refine by Job Title/ Department • Sort by social distance • Display results differently

  29. Indexing Custom DataProtocol Handler • MOSS ships with support for • Web Content, NTFS File Shares, Exchange Public Folders, Lotus Notes DBs, SharePoint Content, SharePoint Profiles, Business Data Catalog • Develop a Protocol Handler to gather data from custom repositories • e.g. Vorsite for Documentum • Connects to a content source and enumerates the documents • Interfaces are the same as in SPS 2003 • New registry path: • Register PH under HKLM\Software\Microsoft\Office Server\12.0\Search\Setup\ProtocolHandlers

  30. Indexing Custom DataIFilter • Install OneNote IFilter (requires OneNote on the server ) • Install PDF IFilter (64 bit now available) • Develop IFilter for custom file formats • Reads a document and extracts the plain text content and properties for the indexer to index • Support reading from streams

  31. Indexing Custom DataBusiness Data Search • Integration without writing code • Information in LOB systems is often hard to access • MOSS 2007 can bring that data to your users • Data is accessed through the Business Data Catalog • Exposed through Search, Meta Data, BDC web parts • Once a web service or a relational data source is registered with the BDC, search can easily index the data • No need to write code • Highly customizable results • Integrated with scopes and search center

  32. Security • Built-in Query-time security trimming (Same as SPS 2003) • File shares, WSS/SPS 2003, Exchange, Lotus Notes(via mapping) • New! Support for result time custom security trimming • ISecurityTrimmer interface (Microsoft.Office.Server.Search.Query namespace) • Implement Initialize() and CheckAccess() • Add the custom security trimmer assembly to the GAC • Register the security trimmer using stsadm command

  33. New Federation Capability

  34. Federation Overview • Enables the display of results from other search engines or applications to be displayed alongside local results • Search Server will • Send a query to other search engines or applications • Format and render the results • Work out of the box or with minimal effort with many existing search engines and applications • Search Server will not • Aggregate multiple result sets into a single result set • Relevance rank results from other search engines or applications

  35. Federated Locations • Each search engine or application must be configured as a Federated Search Location • Each Federated Search Location • Defines how and when queries will be federated to the location • Controls the formatting of results • Defines authentication settings • Can be connected to one or more Federation Web Parts to render results • Is easily imported and exported as a Federated Location Definition file (.FLD)

  36. Supported Location Types • OpenSearch 1.0/1.1 • Query is sent in a parameterized URL • http://search.live.com/results.aspx?q={searchTerms} • {searchTerms} is replaced with query terms • Results must be returned as XML • Local Search Index • Query is sent through the search object model • {searchTerms} scope:customers • {searchTerms} is replaced with query terms • Results are returned as XML

  37. A Note On OpenSearch • Standard created by Amazon A9 for search syndication and aggregation • An exported Federated Location Definition file is >= an OpenSearch Description Document • Search Server extends the OpenSearch schema to include properties such as; • Triggers • XSL • Location Type • More Results Link… • See www.opensearch.org for more info

  38. Location Triggers • Control when to send query terms to a location based on the terms submitted • Always - Will always send all the query terms to the location • Prefix - If the prefix matches will only send the query terms after the prefix to the location • Pattern - Will send some or all of the query terms based on the regular expression match. A pattern trigger can be used to build complex triggers including “OR” statements

  39. Federation Web Parts • Federated Results Web Part • Connected to a single Federated Location • Displays the top X results returned from the location • Top Federated Results Web Part • Connected to multiple Federated locations • Displays the top X results from the first location to return a result in the order of the configured locations • Neither Web Part will render if the location is triggered but it returns zero results

  40. Rendering Results • Built in XSL for • OpenSearch Locations that return results as RSS or ATOM • Local Search Index results • Built in XSL can be customized or replaced • Configured in the Location Definition and can be overridden on individual Web Parts • Separate XSL definition for both of the Federated Results Web Parts • “More Results” Link Template available for click through to HTML results

  41. Authentication • Three modes of authenticating to a location • Anonymous – No credentials required • Corporate – Shared credentials for every user • User – Per user credentials • Per user credentials requires custom work • Code to capture credentials in the UI • Code to store credentials if required • Code to retrieve stored credentials if required • Sample code will be available on MSDN by RTM • Exception is Kerberos which does work OOB • Per user credentials are sent to the location in the correct format automatically

  42. An Example: www.live.com • How to connect Search Server to Live Search • Query Template • http://search.live.com/results.aspx?q={searchTerms}&format=rss • “More Results” Link Template • http://search.live.com/results.aspx?q={searchTerms} • Works without any extra effort because live.com can • Process a query in a URL • Return results formatted as XML (RSS) • Be accessed anonymously • There are many other search engines and applications that provide the same connectivity

  43. Federated Search Connectors • Develop or purchase if the location does not support one or both of the following • Process a query in a URL parameter • Return results as XML • Federated Search Connectors do one or both of the following • Accept a query as a URL parameter and convert it to a format compatible with the location • Convert and render results in XML • Developed as a web page (aspx) • Packaged and deployed as a Solution Deployment Package

  44. An Example: SQL Server • Connect Search Server to the full text search engine in SQL Server • Cannot send a query to SQL in a URL • Build an ASPX page that • Provides a URL for the Query Template • Extracts the {searchTerms} • Contains code to run the query against SQL • Formats and renders the results as XML (RSS) • If required include code to leverage either corporate or per user authentication • Packaged up and installed as a Solution Deployment Package

  45. Connector Gallery • Federated Location Definition Gallery • Linked from within the admin UI • Selection of FLD’s to download and import from Microsoft and Community submissions • Quick, easy and free • Federated Search Connector Gallery • Partner built Federated Search Connectors • Primarily for LOB applications and services • Available for purchase

  46. Summary • The user interface is easily customized to achieve a different look and feel • It’s easy to extend search to develop custom applications, local or remote • You can plug in any data source and search it securely
