|
|
|

You can run the loader in one of two modes: "single" and "elements".
|
||
|
|
If you use "single" mode, the document will be returned as a single
|
||
|
|
langchain Document object. If you use "elements" mode, the unstructured
|
||
|
|
library will split the document into elements such as Title and NarrativeText.
|
||
|
|
You can pass in additional unstructured kwargs after mode to apply
|
||
|
|
different unstructured settings.
