There is only 1 document in the main result set.The expanded section is
empty.

You should be able to use collapse/expand with one result.
Does the document in the main result set have group members that aren't
being expanded?

If I want to group the results (by a certain field) even if there is only

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?

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?
