Google Search Appliance: Search Protocol Reference Appendices 111

Examples of Rules

Because the document

http://www.foo.com/example/foo.html

matches the URL pattern in rule 1,

the search appliance first checks for the date in the title of the document. The URL doesn’t match rule 2,

so the search appliance checks against rule 3. If the search appliance is unable to find a valid date in the

title or the URL, the search appliance looks for the date in the meta tag named publication_date

according to rule 3. If the search appliance is unable to find a valid date in the meta tag, the search

appliance defaults to the last modified date of the HTTP server, according to rule 5.

The search appliance extracts the date from the

http://www.foo2.com/archives/20040605/

abc.html

URL.

Because the document

http://www.foo.com/foo.html

does not match the URL pattern in rule 1, the

search appliance looks for the date in the meta tag, according to rule 3 and defaults to rule 5 if the

search appliance cannot find a valid date in rule 3.

For the document

http://www.foo2.com/foo.html

, the search appliance looks for the date in the

body and defaults to the last-modified date.

For the document

http://www.foo3.com/foo.html

, the search appliance looks for the date only on

the last-modified header as it only matches the URL pattern of rule 5.

Appendix D: Compressed Results

The Google Search Appliance supports serving compressed results.

The search appliance serves compressed results to browsers that support compression. The browser

must send the following HTTP header to the search appliance:

Accept-Encoding: gzip

The search appliance will then serve compressed results. The browser uncompresses the results.

This applies to both XML and XSLT-transformed results. If the

Accept-Encoding: gzip

header is not

present, the results are not compressed.
