Google Search Appliance Connectors Administration Guide - Manual (Page 8)

Off-Board installation
All Connectors 4.0 are installed on a separate host server rather than the search appliance
itself. For more details on this topic, see
Download the connector software .
Connector configuration
Because Connectors 4.0 are not built-in the search appliance, they are not configured
through the search appliance Admin Console, as in previous releases. Configuration is
handled in the adaptor-config.properties file. In release 4.0, “adaptor” is the internal
name of the architecture used by the connectors.
Crawl configuration
As part of deploying a connector, you configure crawl of repository content by using the
search appliance Admin Console. Once crawling starts, you can use the search appliance’s
robust features for monitoring and fine-tuning crawl. Take note that Connectors 4.0 crawl
content according to the crawl schedule that is configured in the Admin Console.
Because some repositories make it easy to notice what has changed recently, adaptors for
those repositories can inform the GSA immediately when things happen, and even force
the GSA to immediately recrawl a document because the adaptor knows that document
was modified recently. This can allow the GSA to pick up changes to a repository with very
low latency, but is not required for correct operation.

Crawl .
Automatic updates every 15 minutes
Every 15 minutes, the Connectors for SharePoint, File Systems, and Active Directory provide
recent changes to the GSA. You can change the default time interval between updates by
editing the adaptor.incrementalPollPeriodSecs
configuration option .
Support for early binding only
Connectors 4.0 enable support for authorization by early binding only; late binding is not
supported. If your implementation requires late binding, Google recommends using a
previous version of connectors.
