If I want to group the results (by a certain field) even if there is
only 1 document, I should use the group parameter instead?
The requirement is to group the result of product documents by their
supplier id.
"&group=true&group.field=P_SupplierId&group.limit=5"
Is it true that the performance of collapse is better than group
parameter on large data set, say 10-20 million documents?

The expanded section will only include groups that have expanded documents.
So, if the document that in the main result set has no documents to expand,
then this is working as expected.

Hi
I have a query which return 1 document.
When I add the collapse and expand parameters to it,
"&expand=true&expand.rows=5&fq={!collapse%20field=P_SupplierId}", the
expanded section is empty (<lst name="expanded"/>).
Is this the behaviour of collapse and expand parameters on result which
contain only 1 document?
