ECS 3.5.0.1 Administration Guide

Metadata search fields

When you set the Metadata Search option to On for a bucket, objects in the bucket can be indexed based on their metadata fields. S3 object clients can search for objects based on the indexed metadata using a rich query language.

Each object has a set of system metadata that is automatically assigned, and can also have user assigned metadata. Both system and user metadata can be included in the index and used as the subject of metadata searches.

When metadata search is enabled on a bucket, you can select System or User as the metadata search Type. When you select a metadata search Type as System, metadata that is automatically assigned to objects in a bucket is listed for selection in the Name drop-down menu.

When you select a metadata search Type of User, you must specify the name of the user metadata to create an index for. You must also specify its data type so that ECS knows how to interpret the metadata values provided in search queries.

You can read more about the metadata search feature in the ECS Data Access Guide, available from https://www.dell.com/support/.
