Specify Metadata Fields

• To search common metadata headers, use the following syntax:

  {metadata-key}{supported SQL operation}{search value}
  

  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}
  

  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}
  

  Example

  tags.type = color
