Google Search Appliance Connectors Administration Guide - Manual (Page 11)

Configuration properties file
Configuration is handled in the adaptor-config.properties file. Each connector
installation procedure in this documentation contains steps for creating its adaptor-
config.properties
file and adding minimal variables to make the connector
operational. For example, after you create the configuration file, you need to add the
server.port
variable to point to the retriever port.
For more information about configuration, see the section that pertains to your connector.
Additionally, there are common configuration variables, which are used by all connectors. If
you do not indicate values for these variables, defaults are used. For more information
about this topic, see
Common configuration options .
Repository content relevancy
The search appliance determines the relevancy in search results of a document that it
crawls on the web by using a "page rank" algorithm, which is based on an analysis of
hyperlinks among documents. A search appliance administrator can view the relative page
rank of a document by using the Index > Diagnostics > Index Diagnostics page in the
Admin Console.
By default, the search appliance sets the relevancy of a document that it crawls in a
repository by using a "content rank" algorithm, which is based on analysis of the
document's content. If a document has a content rank, its relative page rank on the Index >
Diagnostics > Index Diagnostics page is zero.
The configuration variable gsa.scoringType controls whether the search appliance uses
a content rank algorithm or page rank algorithm for repository content. Valid values for
this variable are:
● content (content rank)
● web (page rank)
If the connector uses the web scoring type, you must add the connector root URL as a
Start URL on the Content Sources > Web Crawl > Start and Block URLs page in the GSA
Admin Console. Otherwise, all documents will have a page rank of 1.
