Hi Joel
Correct me if my understanding is wrong.
Using supplier id as the field to collapse on.
- If thecollapse group heads inthe main result set has only 1document in
each group, the expanded section will be empty since there are no
documents to expandfor each collapse group.
- To render the page, I need to iterate the main result set. For each
document I have to check if there is an expanded group with the same
supplier id.
- The facets counts is based on the number of collapse groupsin the main
result set (<result maxScore="6.470696" name="response" numFound="27"
start="0">)

The way that collapse/expand is designed to be used is as follows:
The main result set will contain the collapsed group heads.
The expanded section will contain the expanded groups for the page of
results.
To render the page you iterate the main result set. For each document check
to see if there is an expanded group.

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
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?

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?
