Site Server Search Architecture


As the Internet and information technology have made it easier to generate and
store vast amounts of information, some organizations face the problem of
information overload. For example, in many corporations, workers can receive
information from such sources as Internet newsgroups, list servers, Web page
updates, and discussion groups. Although the availability of information and the
accumulated knowledge helps users make better decisions, it also forces them
to spend more time sifting through information to find the relevant bits and
pieces they need for their job. Users can spend less time sifting and more time
analyzing information if corporations enable them to search across multiple,
indexed data sources.
Microsoft Site Server and Microsoft Exchange Server can perform many
functions within an organization, including providing the infrastructure that
enables organizations to use collaborative applications that access a variety of
internal information sources:


Site Server provides features for full-text indexing, searching, and
delivering information.

Exchange Server provides the collaborative infrastructure and functionality
that enable you to create Internet newsgroups, threaded discussions,
customer contact databases, and custom collaborative applications.

Slide Objective
To outline this topic.
Lead-in
By incorporating Site Server
and Exchange Server, your
collaborative application can
access a variety of
information within an
organization.

Site Server is a Web publishing, search, and delivery tool that works with
Microsoft Windows NT
®
Server and Microsoft Internet Information Server. It
enables you to build Web solutions that you can integrate into your
collaborative application.
Site Server Functions
The categories of Site Server functions include:

Publishing functions. Site Server includes tools that allow site
administrators—or designated users, such as content authors—to submit,
approve, and publish Web content.

Search functions. Site Server indexes documents that are located in file
systems, Web sites, Open Database Connectivity (ODBC) databases, and
mail servers, such as Exchange Server.

Delivery functions. Site Server collects information from multiple sources

and uses Hypertext Transfer Protocol (HTTP) to deliver information to Web
browsers. Site Server also enables site administrators to analyze the
structure and usage patterns of Web sites.

Site Server can also implement content tagging, a structured site vocabulary
that authors use to classify the content they create and specify key words for the
document. When used in conjunction with the knowledge-management
capabilities of Site Server, these tags enable users to find information easily.
Slide Objective
To describe the main
functions of Site Server.
Lead-in
Site Server includes
features that enable
publishing, searching, and
delivering information
through Web browsers.

Site Server version 3.0 includes a search component called Site Server Search
that provides site-administration tools for gathering and indexing information
and creating keyword-search capabilities on Web sites. These keyword-search
capabilities enable users to make highly specific queries to find and retrieve the
information they need.
The most efficient way to use Site Server Search is to build searchable
document catalogs, which are indexes that contain information about
documents, including key words and the location of each document. Catalogs
can index many types of documents, such as Microsoft Word documents,
e-mail messages, text files, Hypertext Markup Language (HTML) documents,
and Microsoft Excel spreadsheets.
With Site Server Search, you can build a catalog from documents found in
different places throughout a company’s file systems, Web servers, ODBC
databases, e-mail servers, and document management systems.
Slide Objective
To depict how Site Server
Search gathers information
from various sources and
makes it available to users
through a search server,

Web server, and browser.
Lead-in
You can use Site Server
Search to gather and index
information.

Before learning about adding search functionality to a collaborative application,
you should understand how Site Server Search finds information in various
sources, indexes the information in catalogs, and searches those catalogs to
quickly find documents.
Finding, Indexing, and Searching Information
To locate information, Site Server Search performs the following functions:

Crawls. Site Server Search gathers content by using the build server to
perform a crawl (a methodical examination) of files located on the Web
servers, file systems, public folders, and ODBC databases that you specify.
Site Server Search creates a transaction log documenting all crawls.
As Site Server Search gathers content, it extracts either full text or attributes
from the documents it finds, depending on your choice. Attributes of
documents can include author, key words, and creation date.


Compiles a catalog index. Site Server Search creates catalog indexes on the
build server.

Propagates the completed catalog. Site Server Search compiles and
propagates the completed catalog to a search server, where it is available for
search queries.

Slide Objective
To depict the architecture of
Site Server Search.
Lead-in
Site Server Search is a
component that enables you
to find, index, and quickly
search for information.

You can configure a search system in many ways. Your choice will affect
network resource usage and depends on factors such as query volume, the
frequency of change, and the geographical dispersion of servers.
Deciding Whether to Use One or Multiple Servers
When planning the configuration of a search system, you need to decide
whether to use one server for both building and searching catalogs or whether
to use multiple servers. It is useful to consider the following three options.
Option 1: Single Server for Building and Searching
Implementing one server that both builds and searches catalogs accommodates
a low volume of users making queries, when changes to the catalog will be
made infrequently, and when the search system is not a critical element of your
collaborative infrastructure.
Option 2: Single Build Server with Multiple Search Servers
Implementing multiple search servers is useful for accommodating a high
volume of users making queries and when implementing a search system that
requires a high degree of fault tolerance. In addition, search systems in which
one server is dedicated to building catalogs and several servers are dedicated to
searching catalogs perform with greater speed.

Option 3: Multiple Build Servers with Multiple Search Servers
Implementing multiple catalog build servers is useful when accommodating
rapidly changing content that you want to crawl frequently (for instance,
Exchange Server public folders) or when you have a network of geographically
dispersed servers—for example, in a situation with several branch offices.
Slide Objective
To provide examples of
server configuration options.
Lead-in
You can configure your
search system to use one or
more servers for building
catalogs and one or more
servers for searching
catalogs.
8 Module 14: Site Server Integration


Changing the Configuration After Implementation
Although Site Server Search allows you to change the configuration of your
search system after implementing it, you should consider the effect any change
will have on the speed of your network. For example, if you have implemented
a search system in which one server handles both build and search functions,
adding search or build servers will increase message traffic on your network.
Setting Resources Usage
On each server, you can set the resource usage separately for building and
searching catalogs. For servers dedicated to one task, you can increase the
resource usage specifically for that task. Or, for servers that perform both tasks,
you can divide the resource usage accordingly.
Setting Administrator Accounts

Each server in a search system must have an account with administrator
privileges and be a member of the Search Administrators, Knowledge
Administrators, or Site Server Administrators permissions group within
Windows NT Server.
Conserving Network Bandwidth
Generally, you can conserve network bandwidth by placing catalog build
servers close to the geographic location where documents are stored and placing
the search servers close to the geographic locations from which users will
search.
