Having the design document will greatly streamline the configuration process because the important questions will have already been answered. This section provides an overview of the configuration approach as well as explanations about certain configuration tasks.

Configuration Overview

After the SharePoint Server 2010 installation has been completed, see the following list that delineates the approach to configuring search. This sequence is significant because certain configurations depend on previous configurations. For example, crawled properties depend on a full crawl, managed properties depend on crawled properties, scopes depend on managed properties, and Site Collection settings depend on scopes.

  • Configure the server topology and farm-wide settings in the Central Administration, Farm-wide Search Administration page.

  • Install third-party iFilters and custom document icons (for example, PDF).

  • From the Central Administration, Search Service Application, configure the following:

    • File types

    • Content sources

    • Crawl schedules

    • Crawl rules

    • Crawler impact rules

    • Authoritative pages

    • Perform a full crawl of content

    • Metadata properties (after full crawl completes)

    • Search scopes

  • From Central Administration, create a search center Site Collection.

  • Within the Site Collection, configure the following:

    • Subsites

    • Search pages and search result pages

    • Search box and search results Web Parts

    • Keywords/best bets

  • In the file system, configure the thesaurus files (optional).

Adding and Configuring Content Sources

Content sources are managed from the Central Administration, Search Service Application, Manage Content Sources page. As described in the previous section, you need to make content available to search queries by crawling the desired content to build the content index so that the information is searchable. Content source can be added and configured to instruct SharePoint to crawl the following types of locations: SharePoint sites, Web sites that are not SharePoint sites, file shares, Exchange public folders, line of business data, and custom repository. You can specify one or more start addresses (URLs) for each content source. A start address is the top of the content’s hierarchy. For example, a root folder in a file share, folder structure is considered a start address.

It is possible have only one content source with many SharePoint start addresses in it; however, this configuration is less flexible than if you were to add a separate content source for each major starting address or SharePoint Web application. Configuring separate content sources provides greater control because it allows you to distinguish content within search scopes, allows you to set unique crawl schedules for different start addresses, and allows you to start and stop crawls on one start address without interrupting others.

Aside from start addresses and content sources, the content source configuration screen also allows you to specify if you would like to crawl only the starting address versus all content below the starting address.

To add a new content source, click the New Content Source link on the Manage Content Sources Screen to get the Add Content Source page. Here, you supply a name for your new content source. From here, you name the content source, provide a start address, and establish the crawl schedules. This process is shown in Figure 1.

Figure 1. Add a content source from Central Administration → Search Service Application → Add Content Source

To configure a content source for SharePoint sites, select SharePoint Sites as the content source type. Enter the URLs in the form, http://intranet. Next, configure the crawl settings and set up a schedule. Keep in mind that a high-intensity crawl may impair that underlying system and the network as well. Unleashing a crawl of network shares could also consume enough bandwidth to be noticeable to workers on the network. Furthermore, if you are backing up the search components of the SharePoint farm or the crawled systems, try to run these backup operations during periods when the crawl is not running. These tips help to reduce contention on the SharePoint servers as well as the servers storing the crawled content. It is also a good practice to document the system operation schedules, such as backups and crawls, and keep this information for reference. On an ongoing basis, crawl behaviors should be measured and monitored. You should keep track of the amount of content in the content sources as well as the amount of time it takes for a crawl to complete on the content source. If a content source grows, backups will take longer, and a job schedule overlap can occur, creating a contention. Reviewing and adjusting the crawl schedules should be considered as a regular responsibility for the support team. Figure 2 shows the crawler impact rules.

Figure 2. Crawler Impact Rules can be used to throttle the intensity of the crawler on each content source and are configured within Central Administration and accessible from the Search Service Application page

Federated Locations

Federated locations allow users to expand their searches to include content that is either in a remote SharePoint environment or retrievable by public Web sites that support OpenSearch 1.0 or 1.1. For example, if Bing is configured as a federated location, users searching from their SharePoint search portals will retrieve results both from the local SharePoint index as well as from Bing. Federated locations are configurable from within the Central Administration → Search Service Application Manage Federated Locations page.

Authoritative Pages and Demoted Sites

Authoritative page settings prioritize locations in the content index so that results from those sites are more (or less) likely to appear ranked highly in the result set. Authoritative page settings are configured in the Search Service Application. Pages can have one of four ranking levels (most authoritative, second level, third level, and sites to demote). By default, all top-level pages for Web applications are added as most authoritative. You can move the top-level pages to other authoritative page levels or remove them from authoritative page settings completely.

When planning authoritative page settings, group sites into the three levels by importance. In addition, group the sites that are not likely to be relevant as sites to demote. Demoted sites will typically appear toward the end of the search results after all other relevance weighting factors have been considered. Don’t try to assign an authoritative page to every single site. Start with obvious ones and then adjust the authoritative page settings based on feedback from users and information in the query logs and crawl logs. Authoritative pages and demoted sites are configurable from within the Central Administration → Search Service Applications → Specify Authoritative Pages screen.

Metadata Properties

When SharePoint crawls content, it includes stored property values in a database; these are crawled properties. Managed properties are the set of properties that are provided to the user as part of the search user experience (the ones that users can filter on, and so on). These map one-to-many to crawled properties. Some managed properties are created by default while in others, administrators must create and map. For example, if you crawl the file extension for documents, you must explicitly specify that the file extension crawled property be included in the index. This is done in the service application, under the metadata properties, crawled properties panel. Next, you must create a managed property called File Extension and map it to the appropriate crawled property. Creating a managed property allows users to leverage the property in keyword searches and allows scopes to leverage the managed property as a filter.

Search Scopes

A search scope provides a way to filter search queries by enabling users to focus their queries on a subset of the total index. Ideally, a search result will appear in the top 20 results when a user issues a query. By providing scopes, users can easily apply filters to their initial queries, making this benchmark much easier to reach.

Scopes can be configured to filter search results by content address, managed property (for example, issue status = unresolved), or content source. For example, a scope might allow a medical doctor to search on all items in the Medical Records Scope, where the Medical Records scope limits the results to items that are documents, located in a Records Center, having the file extension of PDF.

Note

Scopes may be created within the Search Service Application as a shared scope or within a Site Collection as a local scope.


To help determine your search scopes, review your information architecture to identify Content Types and properties that people want to search. Create shared scopes for content in the information architecture that is relevant for more than one Site Collection being hosted in the farm.

To create a search scope, go to Search Service Application within Central Administration. Click View Scopes. Click New Scope. Enter a title, description, and keep the default results page. Once the scope is created, click Add rules.

Search scopes can contain one or more rules that are applied to all content in the currently selected search scope to determine what is included in search results.

You can set rules by

  • Web address (location)

  • Properties (managed properties)

  • Content source (why it is beneficial to be using separate content sources for start addresses)

  • All content (everything in the index)

For example, to set up a scope that only returns information from a specific site, add a Web Address rule where the Folder equals the site URL. This will provide a filtered search list that is scoped to a specific set of content.

Search User Interface

Once the search service application is configured, the next step is to create the user interface for search. When designing the search experience, a decision that needs to be made is whether to create a stand-alone search portal or integrate search features into an existing portal, such as an intranet or content management portal. The Search Center site templates may be used in either case. Once the search site structure is determined, there are numerous components within the Site Collection that combine to make up the overall user experience by providing controls to the user for submitting queries as well as the pieces needed to view and interact with results. The components of the search results page in Edit mode include

  • Search pages and search Web Parts (basic, advanced, people)

  • Search results pages and search results Web Parts

  • Scope display groups

  • Search keywords

Keywords and Best Bets

Keywords are words or phrases that SharePoint administrators have identified as important. They provide a way to display information and links on the initial results page manually. Created at the Site Collection level, keywords help to prioritize content during search queries to display high-relevance content more prominently in search results. Each keyword should have a definition of the keyword that appears in search results, one or more synonymous search terms, and one or more best bets, which are the URLs that administrators specify as being most relevant for a particular keyword phrase.

Searches that match keywords (or synonyms of keywords) show the specific preselected content (definition(s) and best bet(s)) at the top of search results. Best bets are used highlight or promote search results that the search administrator has determined are more relevant for users of a collection. You should choose obvious keywords to start, leveraging best bets to publicize very popular sites and continue to monitor the effectiveness of the chosen best bets over time.
