Importan t Module 6: Adding and Managing External Content 1 Overview  Components of a SharePoint Portal Server Search  Adding Content Sources  Managing Content Sources *****************************I LLEGAL FOR N ON -T RAINER U SE ***************************** Microsoft ® SharePoint ™ Portal Server 2001 stores content that is both internal and external to the workspace. A content source is used to specify a set of content that is stored outside the workspace. The Microsoft Search (MSSearch) service is a full-text indexing and search engine that is used to crawl, retrieve, create and update indexes for this content. This module discusses this process and examines the use of content sources for accessing content that is external to the SharePoint Portal Server computer. After completing this module, you will be able to:  Describe the components that are used in the searching and indexing features of SharePoint Portal Server.  Define content source and describe the types of content that are supported, how a content source is used, and how to add a content source.  Manage a content source by setting schedules, scope, and rules, and describe additional functions that apply to content sources. Topic Objective To provide an overview of the module topics and objectives. Lead-in In this module, you will learn about adding and managing content with SharePoint Portal Server. 2 Module 6: Adding and Managing External Content    Components of a SharePoint Portal Server Search  The Gatherer  IFilters  Word Breakers and Noise Words  Plug-Ins  Indexing Database *****************************I LLEGAL FOR N ON -T RAINER U SE ***************************** This topic provides an overview of the technology that is used in the searching and indexing features of SharePoint Portal Server. These components are used to create and manage content sources. Topic Objective To outline this topic. Lead-in In this topic, we will examine the components of MSSearch. Module 6: Adding and Managing External Content 3 The Gatherer Accessing Accessing Indexing Indexing Filtering Filtering Filter Daemon Process  Core Component of MSSearch  Manages How Content Is Accessed, Filtered, and Indexed  Includes Native and Registered Protocol Handlers *****************************I LLEGAL FOR N ON -T RAINER U SE ***************************** The Microsoft Gatherer performance object is the core component of MSSearch. As SharePoint Portal Server processes transactions on your system, it generates performance data that Windows 2000 can track and log. This data is described as a performance object and is typically named for the component generating the data. The Gatherer manages the way that content is accessed, filtered, and indexed. How the Gatherer Works The Gatherer runs inside MSSearch and interacts with a separate filter daemon process (mssdmn.exe) that performs data access and content filtering. The following steps describe how the Gatherer works: 1. The filter daemon uses protocol handlers and IFilters to extract data. These filters are data type–specific components that SharePoint Portal Server uses to communicate with and filter the documents in the content source. 2. The Gatherer runs the data through a series of plug-ins to process and filter the data. Plug-ins are used to interpret the data and properties as it is pulled from the documents in a content source. 3. The data passes through the plug-ins before the index is created and the document properties are saved to an index database (Microsoft Jet property store). A Jet property store is separate from the Microsoft Web Storage System used by SharePoint Portal Server. Topic Objective To explain the function of the Gatherer. Lead-in In this topic we will examine the Gatherer, a core component of SharePoint Portal Server MSSearch. Note 4 Module 6: Adding and Managing External Content Using Protocol Handlers to Access Data Store Content The Gatherer accesses documents in a data store by using the appropriate protocol by way of a protocol handler interface. The protocol handler, which has no relation to network protocol, is an interface between the index and SharePoint Portal Server. When the Gatherer processes a Uniform Resource Locater (URL) during indexing, the filter daemon determines which protocol handler to use based on the URL prefix, loads the associated dynamic link library (DLL), and passes the URL and security credentials to the protocol handler. Native Protocol Handlers SharePoint Portal Server includes native protocol handlers, or handlers that ship with the product, for Hypertext Transfer Protocol (HTTP), file, Microsoft Exchange 5.5, Microsoft Exchange 2000 Server, and Lotus Notes. Exchange 2000 and SharePoint Portal Server share the Web Storage System technology and the same protocol handler. This protocol handler accesses a local Web Storage System by using Microsoft OLE DB Provider for Exchange 2000 Server (EXOLEDB) and uses Web Distributed Authoring and Versioning (WebDAV) to access the Web Storage System on a remote Exchange or SharePoint Portal Server computer. Registered Protocol Handlers The following table lists the registered protocol handlers that are included with SharePoint Portal Server. Prefix DLL ProgID File Mssph.dll MSSearch.FileHandler.1 HTTP Mssph.dl MSSearch.HttpHandler.1 Exch Mssexph.dll MSSearch.MapiHandler.1 PKM Exstore Pkmexsph.dll PKM.ExstoreHandler.1 Notes Notesph.dll MSSearch.NotesHandler.1 Gatherer Project A search application can have one or more Microsoft Gatherer Projects performance object. Gatherer Projects are located inside a search application, such as SharePoint Portal Server. SharePoint Portal Server has one Gatherer Project for each internal or external workspace. These workspaces have their own settings, such as indexing schedules. The Search services uses Gatherer Projects to keep each workspace separate so it can have its own schedule. A SharePoint Portal Server workspace is a Gatherer Project with its own index. Each Gatherer Project contains its own set of build parameters, crawl restrictions, and plug-ins. Each Gatherer Project contains its own run-time transaction log containing all URLs to be crawled and maintains its own statistics.

How IFilters Work During the filter daemon process, IFilters open data streams and expose the data so that it can be indexed. In particular, the Hypertext Markup Language (HTML) filter strips a document of all HTML tags and emits various HTML syntactic elements as properties, such as author or title, and also emits the body text. Each file type, indicated by its file extension, has an IFilter associated with it. SharePoint Portal Server provides IFilters for HTML, Microsoft Office, text, Multipurpose Internet Mail Extensions (MIME) and Tagged Image File Format (TIFF). You should convert documents created using Office applications to Office 95 or later. The office IFilter would not expose document properties of older Office documents. Topic Objective To explain the function of IFilters. Lead-in In this topic we will examine how filters extract content and properties from documents for indexing.
