6.10 April 2011

Kerberos Crawling

In release 6.10, the Google Search Appliance supports Kerberos-based access for crawling. Before enabling Kerberos-based crawling, configure Kerberos for serving on the Kerberos Based tab of the Serving > Universal Login Auth Mechanisms page. After you configure Kerberos for serving, you can enable Kerberos crawling on the Crawl and Index > Crawler Access page.

For more information about enabling Kerberos crawling, click Help Center > Crawl and Index > Crawler Access in the Admin Console.

Query Settings Page

In previous search appliance releases, you configured query expansion by using the Serving > Query Expansion page in the Admin Console. Starting with release 6.10, this page has a new name: Serving > Query Settings. In addition to supporting query expansion, this page now also provides the following new features:

  • Support for stopwords files. A stopword is a search term that is ignored by the search appliance.
  • An option for increasing the maximum number of terms in a search query.
  • An option for restoring missing snippets in search results.

For information about these new features, click Help Center > Serving > Query Settings in the Admin Console.

Apply Different Dynamic Navigation Configurations to Different Front Ends

In the previous search appliance release, you could create one dynamic navigation configuration and apply it to different front ends. In release 6.10, by using theServing > Dynamic Navigation page, you can configure different dynamic navigation configurations and apply the configurations to different front ends.

For information about creating dynamic navigation configurations and applying them to front ends, click Help Center > Serving > Dynamic Navigation in the Admin Console.

Increase the Maximum Number of KeyMatches

By default, the Google Search Appliance only returns a maximum of three KeyMatches for a search. In release 6.10, you can increase the maximum number of KeyMatches returned up to 50 by using the numgm parameter, which is described in the Search Protocol Reference.

Add Standard Email Headers and Footers to Alerts

In release 6.10, you can include a standard email header and footer in alert emails sent from the search appliance by using options on the Serving > Alerts page. For information about adding email headers and footers, click Help Center > Serving > Alerts in the Admin Console.

Set the Maximum File Size for the Crawler to Download

In release 6.10, the Google Search Appliance provides an option for changing the file size limits for downloading when crawling documents.

For information about changing the maximum files sizes to download, click Help Center > Crawl and Index > Host Load Schedule in the Admin Console.

Support for Secure Feeds

In release 6.10, the search appliance supports HTTPS access to the Feedergate server, enabling you to upload an XML feed file by using a secure connection with or without client certificate authentication. By default, the search appliance supports HTTP (non-SSL) access to the Feedergate server. You can disable or re-enable HTTP (non-SSL) access to Feedergate by using the Administration > SSL Settings page.

For information about disabling or re-enabling HTTP (non-SSL) access to Feedergate, click Help Center > Administration > SSL Settings in the Admin Console.

  • Using the default certificate authorities without uploading any of your own certificate authorities
  • Using only your uploaded certificate authorities without using the default ones
  • Using both the default and uploaded certificate authorities

For information about selecting one of these options, click Help Center > Administration > Certificate Authorities.

6.12 August 2011

Dynamic Navigation for Secure Search

Dynamic navigation helps user explore search results by presenting navigation options based on metadata attribute values. Starting with release 6.12, you can enable dynamic navigation for secure search. If you enable it, the search appliance only uses documents that the user is authorized to see to generate navigation options. To configure dynamic navigation for secure search, use the Serving > Dynamic Navigation page.

For information about dynmaic navigation for secure search, click Help Center > Serving > Dynamic Navigation in the Admin Console.

Nested Metadata Queries

In previous search appliance releases there were restrictions for nesting meta tags in search queries. In this release many of those restrictions are lifted. For information about nested metadata queries, see "Nested Boolean Filtering Using Meta Tags" in the "Search Protocol Reference."

LDAP Authentication with Universal Login

In release 6.12, you can configure a Universal Login credential group for LDAP authentication by using the new LDAP tab on the Serving > Universal Login Auth Mechanisms page in the Admin Console. Also on this tab are options for enabling LDAP for a search appliance, as well as group lookup (both formerly on theAdministration > LDAP Setup page).

For information about using this tab, click Help Center > Serving > Universal Login Auth Mechanisms > LDAP.

Index Removal and Backoff Intervals

When the search appliance encounters a temporary error while trying to fetch a document during crawl, it retains the document in the crawl queue and the index, and schedules a series of retries after certain time intervals, known as "backoff" intervals, before removing the URL from the index. In release 6.12, you have the option of using the search appliance default settings for index removal and backoff intervals, or configuring them.

To configure settings, use the options in the Configure Backoff Retries and Remove Index Information section of the Crawl and Index > Crawl Schedulepage in the Admin Console. For more information about configuring settings, click Help Center > Crawl and Index > Crawl Schedule in the Admin Console.

Specify URLs to Crawl Immediately in Feeds

Release 6.12 provides the ability to specify URLs to crawl immediately in a feed by using the crawl-immediately attribute. For information about the crawl-immediately attribute, see the "Feeds Protocol Developer's Guide."

X-Robots-Tag Support

The search appliance support the the X-Robots-Tag directive in an HTTP header response. Use this directive to prevent the search appliance crawler (as well as other crawlers) from indexing or following links in a specific non-HTML document.

For information about the X-Robots-Tag directive, see "Using X-Robots-Tag to Control Access to Non-HTML Documents" in "Administering Crawl: Preparing for a Crawl."

6.14 November 2011

Flexible Authorization

Beginning with release 6.14, the Google Search Appliance supports flexible authorization, a new model for performing authorization checks. Flexible authorization gives search appliance administrators more control over authorization by enabling them to:

  • Specify authorization mechanisms in the environment
  • Customize which authorization mechanisms handle which URLs
  • Set the precedence of mechanisms for performing authorization checks

As a search appliance administrator, you can choose to enable flexible authorization or continue to use the search appliance's legacy authorization. However, there is one exception: SMB URLs, which are only handled by the search appliance's legacy authorization.

To configure flexible authorization, use the new Serving > Flexible Authorization page. For information about this page, click Help Center > Serving > Flexible Authorization.

Early/Late Binding for Policy ACLs and Per-URL ACLs

Flexible authorization provides an option for enabling late binding for policy ACLs and per-URL ACLs. If you enable late binding for policy ACLs and per-URL ACLs, the search appliance accepts deny decisions only for these mechanisms. For allow and indeterminate decisions, the search appliance applies each subsequent associated mechanism in the authorization mechanisms list in order until one of them returns a decision other than indeterminate.

For information about enabling late binding for policy ACLs and per-URL ACLs, click Help Center > Serving > Flexible Authorization.

Perimeter Security

Release 6.14 provides perimeter security, which ensures that the search appliance doesn't serve any results without user authentication. When perimeter security is enabled, the search appliance prompts the user for credentials when she first submits a search request. The search appliance authenticates the user by using the mechanisms that are configured for Universal Login.

To configure perimeter security, use the Serving > Universal Login page. For instructions for configuring perimeter security, click Help Center > Serving > Universal Login.

Query Suggestions Export

Release 6.14 introduces a new Admin Console page, Serving > Suggestions. This page enables you to see which query suggestions the search appliance is using by exporting them. The search appliance also has a suggestions blacklist, which contains words that are excluded from query suggestions. If you want to change the suggestions blacklist, you can export it, edit it, import it to the search appliance.

For information about exporting query suggestions and the suggestions blacklist, click Help Center > Serving > Suggestions.

Synonyms Support in Dynamic Navigation

In release 6.14, the search appliance enables you to configure query expansion for configured dynamic navigation attributes.

For information about this topic, see "Configuring Query Expansion for Dynamic Navigation."

Query Expansion for Meta Tags

Starting with this release, you can set up a query expansion policy for meta tags by using the Serving > Front Ends > Filters page. Use a query expansion policy for meta tags to select the parts of the name/value pair in a meta tag that the search appliance expands with synonyms.

For information about query expansion for meta tags, click Help Center > Serving > Front Ends > Filters.

Click-Jacking Defense

Click-Jacking (sometimes called UI Redress) is a type of web attack where an attacker modifies the user interface of a target web site so that a victim does not realize that he is taking an important action. With release 6.14, the search appliance can prevent these types of attacks when Click-Jacking Defense is enabled, which is the default. You can change the setting for Click-Jacking Defense by using the Serving > Query Settings page.

For more information about click-jacking defense, click Help Center Serving > Query Settings.

Crawl Coverage Tuning

Release 6.14 introduces a new Admin Console page, Crawl and Index > Coverage Tuning. Use this page to control the number of URLs the search appliance crawls for a site. For example, you might want to limit the number of URLs the search appliance crawls in one site and allocate more space for other sites.

For information about crawl coverage tuning, click Help Center > Crawl and Index > Coverage Tuning.

Infinite Space Detection

In "infinite space," the search appliance repeatedly crawls similar URLs with the same content while useful content goes uncrawled. Starting with release 6.14, you can prevent crawling of duplicate content to avoid infinite space indexing by using the Crawl and Index > Duplicate Hosts page.

For information about configuring infinite space detection, click Help Center > Crawl and Index > Duplicate Hosts.

Lock on Database Crawling

In this release, you can prevent the Google Search Appliance from deleting database content from the index when its PageRank™ is low and the index has reached its license limit by using the Lock documents checkbox on the Crawl and Index > Databases page.

For more information, click Help Center > Crawl and Index > Databases.

External Metadata at Crawl Time

Release 6.14 supports adding external metadata at crawl time. This process is useful for indexing metadata for non-HTML documents where it is not possible to include metadata in the document itself. To use this method of indexing external metadata, the web service that stores the content needs to be designed to generate the optional X-GSA-External-Metadata HTTP response header.

For more information, see "External Metadata Sent in an HTTP Header" in "External Metadata Indexing Guide."

Document Date Configuration

New options on the Crawl and Index > Document Dates page enable you to define the date format that's used for documents in a specified URL pattern.

For information about configuring document dates, click Help Center > Crawl and Index > Document Dates.

Connector Manager Log Levels

In this release, the Connector Administration > Connector Managers page includes new options for controlling the connector log level and feed log level.

For information about changing log levels, click Help Center > Connector Administration > Connector Managers.

Connector Advanced Properties

With release 6.14, the Connector Administration > Add Connector page provides a new Advanced Properties option, which enables you to change any advanced properties of a connector type while configuring a connector instance of that type.

Mirroring for GSA Unification

In release 6.14, the search appliance enables you to set up mirroring for a node in a unification configuration by designating it as a "Replica" node.

For information about how to set this up, see "Configuring GSA Unification."

Multinode Support for Google Apps Personal Content

In previous releases, GSA mirroring and GSA distributed crawling and serving could not integrate personal content from the Cloud Connect > Google Apps Content into search results. In release 6.14, this limitation is removed and they can integrate personal content into search results.

Password Complexity Enforcement

Release 6.14 introduces password complexity enforcement through strict password checking options on the Administration > User Accounts page. When Use strict password checking is enabled, certain policies apply to administrator and manager accounts for the Admin Console. For example, passwords changes are checked for appropriate password length, password character mix, and password reuse, as well as other policies.

For information about strict password checking, click Help Center > Administration > User Accounts.

Cookie Domain Configuration

By default, the cookie domain is set to the search appliance's host name, which means that a browser can send a cookie only to one search appliance. In this release, you can use the Administration > System Settings page to configure the cookie domain to enable a cookie to be sent to more than one search appliance in the configured cookie domain, such as in GSAn and Unification configurations.

For information about configuring the cookie domain, click Help Center > Administration > System Settings.

Login Terms

If you have additional terms or conditions for using the Admin Console, you can force the administrator to agree to this set of terms before she is able to access the Admin Console. To do this, use the new Administration > Login Terms page in the Admin Console.

For more information, click Help Center > Administration > Login Terms.

Query Prefix Changes

Starting with release 6.14, the prefix filetype filters search results to include only documents with the specified MIME content type. The prefix ext fiters search results to include only documents with the specified file extension. 

For more information, see "Special Query Terms" in the "Search Protocol Reference."
