DocSplitFilter

DocSplitFilter#

class DocSplitFilter(config)#

Bases: Filter

The doc_split Filter splits a single Document into many via iterable fields of the same length.

Input - all input fields need to be of type list [ object ].

Output - The output fields are going to be of type object.

Parameters:

  • type (str) – doc_split

  • fields (list) – Fields to split on (must all be same length)

  • flatten (bool, False) – Whether or not to flatten the split fields

  • copy_fields (bool, False) – Whether to refer or copy the other fields of the document to the new generated documents. If you expect to mutate the other fields of the generated document in subsequent steps, then set this parameter to true. However, please note that this may come with a performance penalty when the document has many number of elements for the defined fields.

Example

{
    "step": "filter",
    "type": "doc_split",
    "fields":["sentences"]
}
