New and changed features

The following sections describe new and changed features in software release 7.6.50:

Disable host load limit for hosts with same IP address

In release 7.6.50, you can control whether the search appliance uses the lowest host load limit for all hosts that DNS resolves to the same IP address. If you disable this option, the search appliance only matches a host to its resolved IP host load if that IP has an explicit host load entry.

You can disable using the lowest host load on the Content Sources > Web Crawl > Host Load Schedule page, by unchecking Use Lowest Host Load Limit for All Hosts with Same IP.

For more information about this feature, see the Content Sources > Web Crawl > Host Load Schedule help page in the Admin Console.

Enable SSLv3 through Admin Console

SSLv3 is deprecated and discouraged. You should use it only for compatibility with legacy systems that do not support TLS 1.0 or higher. In release 7.6.50, SSLv3 is disabled in the search appliance. You can enable SSLv3 for crawling and Onebox requests; you can not enable it for serving.

You can enable SSLv3 from the Administration > SSL Settings page, by checking Enable SSLv3.

Language bundles automatically synced in mirroring configurations

In release 7.6.50, in mirroring configurations, the search appliance automatically syncs the language bundles configuration and data to replica nodes. You can manage language bundles only on the master node.

You enable mirroring from the GSAn > Configuration page. Also see Configuring GSA Mirroring.

Recrawl content on a specified schedule

In release 7.6.50, you can use the GSA Admin Toolkit to automatically recrawl patterns you enter in index diagnostics. To recrawl a specific pattern, use the --recrawl option in It performs similar functionality to manually clicking the Recrawl this pattern option in index diagnostics.

You set the patterns you want to recrawl in the Index > Diagnostics > Index Diagnostics page.

Set wildcard search to include/exclude metadata

In release 7.6.50, you can use a new parameter in search requests, wc_p, to include or exclude metadata from wildcard expansions in search results. Values are:

1--No restriction (default). Content and metadata expansions are returned in results.
2--Only metadata expansions are returned in results.
3--Metadata expansions are excluded from returned results.

This feature applies to wildcard expansions only. It does not apply when matching terms, for example, when using operators such as intext: or inmeta:.

For information about wildcard search, see the Search Protocol Reference.

Use plus (+) character in query expansion files

In release 7.6.50, the search appliance can perform query expansion on words containing the plus (+) character. The + can be in the beginning, middle, or ending of a word, for example:

Google+ can be expanded to include "Google Plus"
+Size can be expanded to include "plus size"
yellow+blue can be expanded to include "green"

You enable query expansion from the Search > Search Features > Query Settings page.

For information about creating query expansion files, see Creating the Search Experience.

Deprecated features


In GSA release 7.6.50, support for SSLv3 is deprecated. It will be removed in a future release.

GSA Unification

In GSA release 7.6, GSA Unification was deprecated. It continues to be deprecated in release 7.6.50 and will be removed in a future release.
