Search Tool Characteristics¶
The S3 Search tool is a Scality API extension to the AWS API. S3 Search complies with AWS S3 search syntax, with certain noteworthy differences. S3 Search is MongoDB-native, and addresses the S3 search through queries encapsulated in a SQL WHERE predicate. It uses Perl-Compatible Regular Expression (PCRE) search syntax.
Searchable Metadata and Tags¶
Because Zenko supports two classes of custom tags, it is not possible to list all the ways to search data in Zenko. At a mimimum, however, files will have the following fields inscribed, and these will be searchable:
- cache-control
- content-disposition
- content-encoding
- dataStoreName
- expires
- content-length
- content-type
- content-md5
- isDeleteMarker
- isNull
- location
- nullVersionId
- owner-display-name
- owner-id
- replication-status
- versionId
Default Amazon S3 metatags:
- x-amz-version-id
- x-amz-server-version-id
- x-amz-server-side-encryption
- x-amz-server-side-encryption-aws-kms-key-id
- x-amz-server-side-encryption-customer-algorithm
- x-amz-website-redirect-location
