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.*"

Custom user metadata must be prefixed with “x-amz-meta-”:

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
