+**Addresses duplicate key error when passed in request parameters and body**
+
+This bug fix handles the issue, when using the POST {resourcetype}/search endpoint to query FHIR resources, the server returns 415 Unsupported Media Type. This is due to repeating a query parameter in the URL query string and the request body. This fix considers all the query parameters from request and body as input.
