Hi Shamik, You should be seeing the same result counts with grouping and the CollapsingQParserPlugin, unless there are null values in the collapse field. Let's see if we can figure out what the issue is.
Can you post the schema.xml field type definition for the ADSKDedup field? Also can you post the full debug output for both queries?
