204 Part III: Planning <strong>and</strong> Deployment<br />

Planning Search<br />

This section describes the components of the SharePoint Portal Server search functionality.<br />

It provides guidelines on planning a customized version of each search<br />

component for your solution.<br />

Overview of Search Functionality<br />

There are four components that contribute to the SharePoint Portal Server search<br />

functionality:<br />

■ Content sources<br />

■ Content indexes<br />

■ Source groups<br />

■ Search scopes<br />

For an in-depth discussion of each of these components, please refer to Chapter<br />

21, “The Architecture of the Gatherer,” <strong>and</strong> Chapter 22, “Managing External Content<br />

in <strong>Microsoft</strong> Office SharePoint Portal Server 2003.” This chapter will discuss the<br />

planning requirements for content indexes only.<br />

SharePoint Portal Server 2003 comes with two content indexes—Portal_Content <strong>and</strong><br />

Non_Portal_Content. You can create additional content indexes as well; however,<br />

keep in mind that each search query has to be run on each index <strong>and</strong> the results<br />

must be aggregated before they are returned to the user. The result is that the more<br />

indexes you have, the longer search results take to generate.<br />

Note Advanced search administration mode should be enabled so that<br />

you can create <strong>and</strong> manage additional indexes. In addition, when you create<br />

content sources, you can specify the index in which the content source will<br />

appear, <strong>and</strong> you can specify the source group.<br />

When planning content indexes, consider the following factors:<br />

■ Number of documents. If the number of documents is very large, you<br />

should consider breaking the content sources into many content sources with<br />

smaller scopes to make the size of the indexes more manageable. This is<br />

important because the index catalogs are copied across the network. Copying
