Default Settings in Discovery Configuration

Voyager's Default Configuration Settings allow you to fine-tune a range of indexing options. This article addresses the Settings tab in the Default Settings section.

To access Default Settings:

• Go to Manage > Discovery > Discovery Configuration > Default Settings 

• Select the Settings tab

Open

Extract Linked Data

Voyager will extract local copies of the LYR and XML files from MXD and GDB layers, where present. Keep in mind that this may require additional storage, depending on the nature of the data.

Index Debug Information

If you are troubleshooting issues with the Voyager support team, use this option to include debug information in the index during the discovery process. 

Index Access Control Information

This setting enables Voyager to add access control list (ACL) information from Windows Active Directory directly to the index for every file discovered. 

If this setting is set to yes, then the 'File system access controls list' option should also be enabled on the Manage > Security > Access page. This option will filter search results to only what a Voyager user has read access according to Windows Active Directory settings. 

Index Extended File Attributes

This will extract extended file attributes from data records. Extended file attributes can include the author of a document, the character encoding of a plain-text document, a checksum, cryptographic hash or digital certificate and discretionary access control information.

Calculate MD5 Checksum

You can accurately detect duplicate data with in your index by comparing MD5 checksums. Note that this calculation is slower than the default methods of detecting duplicates (using a content hash and schema hash), so should only be employed when a high degree of accuracy is needed.

Read XML Metadata

XML metadata often contains information that explicitly augments the attributes that Voyager can glean directly from the items that it ingests. If this option is selected, Voyager will process information from any XML document that accompanies an indexed item according to the XPATH selection rules configured in the Pipeline > Metadata Extraction settings.

Cache All Metadata Files

Voyager can display simple XML metadata in the UI.  This works well when the index and data will stay together. If you intend to index data and show the contents disconnected from the data, you may want to store a copy of the metadata XML in voyager's internal cache.

Process All Records

This setting will force Voyager to create an MD5 checksum/hash for all files discovered regardless of whether Voyager can read the file format. This is useful for identifying duplicate files that Voyager does not yet read.
