Google Search Appliance: External Metadata Indexing Guide 12

Each value has the form: meta-name=meta-value. Both the meta-name and the meta-value are encoded

according to section 2 of RFC3986 (http://www.ietf.org/rfc/rfc3986.txt) (commonly known as percent-

encoding). The search appliance does not transform ‘+’ to space.

The following restrictions apply to this header:

• The meta-value cannot be empty.

• The values for the meta-name and meta-value cannot contain embedded quotation marks.

Document Access Control

The search appliance provides document-level access control to secure the search content. When you

index external metadata, the search appliance applies the following access controls:

• The access control of the external metadata in “Scenario 1” on page 6 and “Scenario 2” on page 7

(where the metadata is stored in a database) is the same as the access control for the associated

primary document.

• The access control of the external metadata in “Scenario 3” on page 8 (where the metadata and the

primary document are stored in the database) is public, which means that it is available to all search

users. Scenario 3 is a bad option for data that needs to be secured.

• The access control for external metadata in “Scenario 4” on page 9 and “Scenario 5” on page 11

(where the metadata is inserted into the feed XML file) is specified in the feed, just as with non-

metadata feeds.
