Metadata Mapper
For a given crawled document, this stage maps a given input field to a given target field.
This stage comes with the following configuration parameters:
Source field: determines which field should be read as an input
Target field: determines the target field to move or copy the source’s content to.
Override existing values: enable this to override values, which might already exist in this document. Otherwise the values will be kept in this field.
Keep original value in source field: this defines whether to move or copy the values from source fields into the target field. If you only want to copy, then turn on this checkbox.
