Specifying Metadata Fields¶
To search common metadata headers, use the syntax:
{metadata-key}{supported SQL operation}{search value}
For example:
key = blueObject size > 0 key LIKE "blue.*"

”:
x-amz-meta-{usermetadata-key}{supported SQL operation}{search value}
For example:
x-amz-meta-color = blue x-amz-meta-color != red x-amz-meta-color LIKE "b.*"
Tag searches must be prefixed with “tags.
”:
tags.{tag-key}{supported SQL operation}{search value}
For example:
tags.type = color
