Hello @895669342, In both SOAP or JSON version of API, you can include a Filter in your request to narrow down the search results.

See section 13.3.1.8 of the TRKD documentation to see the filter structure. For GOL and English you will use ```Value Text = GOL, Class = Any``` and ```Value Text = EN, class = language```

Samples filters:

JSON:
"Filter": [{
  "And": {
   "MetaDataConstraint_typehint": [
    "MetaDataConstraint",
    "MetaDataConstraint"
   ],
   "MetaDataConstraint": [{
     "Value": {
      "Text": "ECI"
     },
     "class": "topics"
    }, {
     "Value": {
      "Text": "EN"
     },
     "class": "language"
    }
   ]
  }
 }
]

SOAP:
<Filter>
  <And xmlns="http://schemas.reuters.com/ns/2006/04/14/rmds/webservices/news/filter">
    <MetaDataConstraint class="Attribution">
      <Value>Reuters</Value>
    </MetaDataConstraint>
    <MetaDataConstraint class="Companies">
      <And>
        <Value>MSFT.O</Value>
        <Value>YHOO.O</Value>
      </And>
    </MetaDataConstraint>
    <FreeTextConstraint where="headline">
      <Value>Merger</Value>
    </FreeTextConstraint>
  </And>
</Filter>

This question shows screenshot from overview tab in support portal. You can see xml or json for any sample shown there simply:

- go to develop tab (to right of "overview" in top right bar)

- select "load from" and choose same example you are interested (everything from overview tab should be listed)

- select "inspect" and it will show you soap/xml

- or select "json" option and reload example, select inspect and it will show all required headers and the json body
