New and Changed Features

The following sections describe new and changed features in software release 7.0:


Entity Recognition

Release 7.0 introduces entity recognition, which enables the Google Search Appliance to discover interesting entities in documents with missing or poor metadata and store these entities in the search index. Once the entities are indexed, you can enhance keyword search by adding the entities in dynamic navigation, which uses metadata in documents and entities discovered by entity recognition to enable users to browse search results by using specific attributes.

To configure entity recognition, use the new Crawl and Index > Entity Recognition page in the Admin Console. To learn more, click Help Center > Crawl and Index > Entity Recognition.

Expert Search

New in release 7.0 is expert search, which enables your users find experts in your organization by searching on keywords. For example, suppose a user needs to find an expert on network security. When the user searches on this term, a list of network security experts appears in a sidebar next to the search results. The list might include photos, names, and phone numbers. There might also be a more detailed list of experts on a separate page that is linked to the search results page.

Experts in your organization are identified by metadata that resides in a collection that contains only profile information. Data sources for this collection can include Microsoft SharePoint, LDAP, or any other profile content with metadata that can be crawled or fed into the search index.

You can determine the profile elements and their layout in both the sidebar and on the detail page when you configure expert search. Because expert search is configured by front end, you can create different configurations for that address the needs and levels of different end users.

To configure expert search, use the new Social Connect > Expert Search page in the Admin Console. To learn more, click Help Center > Social Connect > Expert Search.

Take note that people search is deprecated in release 7.0. However, for compatibility with previous releases, people search options are available from the Social Connect > Expert Search page.

User Results

In previous releases, the Google Search Appliance supported basic user-added results, which gave your users the capability of creating unmoderated search results. Starting with release 7.0, the enhanced user results feature replaces basic user-added results.

The new feature enables you to add user results configurations, where you can specify whether user results are moderated, that is, they require administrator approval before appearing in search results, and which front ends use the configuration. Because a user result configuration can be associated with one or more front ends, you can create multiple configurations with different settings and associate them with separate front ends.

To add user results configurations, use the new Social Connect > User Results page in the Admin Console. To learn more, click Help Center > Social Connect > User Results.

Document Previews in Search Results

In release 7.0 the Google Search Appliance provides document previews, which enable users to view a preview image of a document without leaving the search results. The search appliance supports document previews for Microsoft Word (doc, docx), Microsoft PowerPoint (ppt, pptx), and Adobe Portable Document Format (pdf) documents.

The new document preview module prepares document preview images. When you enable the document preview module and configure a front end to show document previews, a user can view document previews, as well as page through and enlarge them.

To enable the document preview module, use the new Serving > Document Preview Module page in the Admin Console. To learn more, click Help Center > Serving > Document Preview Module.

Translation of Search Results

Starting with release 7.0, the Google Search Appliance can translate titles and snippets in search results, as well as cached documents into the user’s language in real time. The user’s language is determined by the default language set in the user’s browser. When translation is enabled, translation links appear in search results. The user can translate everything on a results page or just individual titles, snippets, or cached documents. You can enable or disable translation for any front end. Take note that translate does not work for the Document Preview feature.

To enable translation, use the Page Layout Helper on the Serving > Front Ends > Output Format page in the Admin Console. To learn more, click Help Center > Serving > Front Ends > Output Format - Page Layout Helper.

Index Limit Settings

By default, the Google Search Appliance indexes up to 2.5MB of each text or HTML document, including documents that have been truncated or converted to HTML. Starting with release 7.0, you can change the default index limit by entering an new amount of up to 10MB.

To change the index limit, use the new Crawl and Index > Index Settings page in the Admin Console. To learn more, click Help Center > Crawl and Index > Index Settings.

Metadata Indexing Configurations

With release 7.0, you can customize configurations for metadata indexing. The Google Search Appliance has default settings for indexing metadata, including which metadata names are to be indexed, as well as how to handle multivalued metadata and date fields. Now, you can customize the default settings or add an indexing configuration for a specific attribute.

To customize metadata indexing, use the new Crawl and Index > Index Settings page in the Admin Console. To learn more, click Help Center > Crawl and Index > Index Settings.

If you have configured multvalued attributes for dynamic navigation in a pre-7.0 release, the search appliance will automatically add these attributes under Index Settings when it is updated to software version 7.0. After your search appliance is running 7.0, you will only be able to add multivalued attributes by using the Crawl and Index > Index Settings page.

Index Compressed Files

Beginning with release 7.0, the Google Search Appliance supports crawling and indexing compressed files in .zip, .tar, .tar.gz, and .tgz formats.

To enable the search appliance to crawl these types of compressed files, use the Crawl and Index > Crawl URLs page in the Admin Console. To learn more, click Help Center > Crawl and Index > Crawl URLs.

Dynamic Navigation Enhancements

In this release, dynamic navigation has been enhanced to support more date formats and multi-valued attributes. Also, dynamic navigation now supports adding attributes based on entities discovered by Entity Recognition.

To learn more, click Help Center > Serving > Dynamic Navigation in the Admin Console.

Access Control List Enhancements

Content systems allow for ACL information to be applied to groups of documents through inheritance. In release 7.0, the Google Search Appliance is able to model a wide variety of security mechanisms by using ACL inheritance for per-URL ACLs. To specify ACL inheritance, use the new acl element, which also provides attributes that enable you to specify a URL, principal (user or group), access (permit or deny), namespace, and case sensitivity.

To learn more about the new acl element and inheritance, see the Feeds Protocol Developer’s Guide.

Also in release 7.0, you can change the number of principals to add to a per-URL ACL by using the Crawl and Index > Host Load Schedule page in the Admin Console. To learn more, click Help Center > Crawl and Index > Host Load Schedule.

Also new in this release, the search appliance can accept per-URL ACLs, along with documents at crawl time, through the X-GSA-External-Metadata HTTP response header. To learn more, see Managing Search for Controlled-Access Content.

Entity Biasing

In support of Entity Recognition, result biasing has been extended to support entity biasing. This feature enables you to increase or decrease a document's score when it contains an entity that matches a specified name:content pair.

To specify your preferred adjustments for entities, select the entities from the pull-down menu on the Serving > Result Biasing > Edit page in the Admin Console. The menu is populated with entities that are added by using the Crawl and Index > Entity Recognition page.

To learn more, click Help Center > Serving > Result Biasing > Edit.

Configure Multiple LDAP Servers

Starting with release 7.0, you can configure multiple LDAP servers on a Google Search Appliance. There is no limit to the number of LDAP server configurations that you can create.

To configure one or more LDAP servers, use the Administration > LDAP Setup page in the Admin Console. To learn more, click Help Center > Administration > LDAP Setup.

Serving Logs

The Google Search Appliance records detailed information in serving logs about how it serves results for every search query. Information from serving logs can assist you in setting up a new security configuration or debugging an existing configuration.

In this release, the Admin Console provides a new page, Status and Reports > Serving Logs, that enables you to view and filter serving logs. To learn more, click Help Center > Status and Reports > Serving Logs.

IPv6 Support

Beginning with release 7.0, the Google Search Appliance supports IPv6. For more information, see Planning for Search Appliance Installation.
