I am using solrnet and I have to group my results by one field "thisfield". In grouping I should return this:

group=true&group.field=thisfield&group.limit=100

In my code I use this:

Grouping = new GroupingParameters()
{
    Fields = new[] { "thisfield" },
    Format = GroupingFormat.Grouped,
    Limit = 100,
},

But this code returns to me nothing, where is my problem? any ideas?

More info from putty:

I need to get this: INFO: webapp=/solr path=/select params={sort=sequentialid+desc,exchangetimestamp+desc&indent=true&q=destination:LUKA+OR+sender:LUKA&group.limit=100&_=1401690365440&group.field=breadcrumbid&group=true&wt=xml} hits=539927 status=0 QTime=76

I am getting this: INFO: webapp=/solr path=/select params={group.format=grouped&sort=sequentialid+desc,exchangetimestamp+desc&start=0&q=((((destination:LUKA))+OR+((sender:LUKA))))&group.limit=100&group.field=breadcrumbid&group=true&version=2.2&rows=15} hits=539927 status=0 QTime=76

Limit = 100, should be Limit = 100 ? – Simcha Khabinsky
No diffrents, comma is not important in last row, I can have it, or not. – geekforfreek
Maybe you are not assigning the Grouping parameter to the Query? Can you post the entire options setup? – Simcha Khabinsky
Options setup? Do you mean my result from logs, I posted in quetion, from putty. First result is from my Solr Admin, second is from my application. – geekforfreek
OK I figure out, it is nothing wrong with my code, problem is with that I am returning List instead Group. – geekforfreek

I don't think you have anything wrong in the query.

Just mind that if you do a grouping query in SolrNet you need to read results from

SolrQueryResults.Grouping.Values

instead of just using SolrQueryResults as a list, because the list will be empty.
