Extract only data (without response element) using MarkLogic search API with REST - rest

Question

When making REST endpoint call to MarkLogic, is there an option to get only the data in the response without the additional metadata?
I am trying to use to make such connections using tools like Tableau, Qlik, Denodo etc
Options I use in the POST body on the URL: http://localhost:8000/v1/search
<search xmlns="http://marklogic.com/appservices/search">
<options>
<extract-document-data selected="all"></extract-document-data>
<transform-results apply="raw" />
</options>
</search>
Result I get:
<search:response snippet-format="raw" total="150" start="1" page-length="10" selected="all" xmlns:search="http://marklogic.com/appservices/search">
<search:result index="1" uri="/doc/21_doc.xml" path="fn:doc("/doc/21_doc.xml")" score="0" confidence="0" fitness="0" href="/v1/documents?uri=%2Fdoc%2F21_doc.xml" mimetype="application/xml" format="xml">
<root>
<col1>data1</col1>
<col2>data1</col2>
<col3>data1</col3>
</root>
<search:extracted kind="element">
<root>
<col1>data1</col1>
<col2>data1</col2>
<col3>data1</col3>
</root>
</search:extracted>
</search:result>
<search:metrics>
<search:query-resolution-time>PT0.0005236S</search:query-resolution-time>
<search:snippet-resolution-time>PT0.0001001S</search:snippet-resolution-time>
<search:extract-resolution-time>PT0.0003971S</search:extract-resolution-time>
<search:total-time>PT0.0021503S</search:total-time>
</search:metrics>
</search:response>
Expected:
<search:extracted kind="element">
<root>
<col1>data1</col1>
<col2>data1</col2>
<col3>data1</col3>
</root>
</search:extracted>
Also, why am I getting data in both extracted and result elements?

Answer 1

Both snippeting and data extraction provide access to content. Use either, or use them for different purposes. If you only like to get extracted data, then use:
<transform-results apply="empty-snippet" />
HTH!

Answer 2

If you want the original documents, specify an Accept header of multipart-mixed and specify only the content value for the a category URI parameter.
See: https://docs.marklogic.com/REST/POST/v1/search
and https://docs.marklogic.com/guide/rest-dev/bulk#id_65903
As an alternative, you may find it easier to provide rows to Business Intelligence Tools by creating TDE indexes and paging over an Optic query with the /v1/rows endpoint.

and https://docs.marklogic.com/REST/POST/v1/rows
Hoping that helps,
