Results Group-By using SolrJ

Hi All,

I am trying to group by results using SolrJ. According to
https://issues.apache.org/jira/browse/SOLR-2637 the feature was added, so I
upgraded to SolrJ-3.4-Snapshot and I can see the necessary method for
grouping in QueryResponse, which is getGroupResponse(). The only thing left
that I don't understand is where do I set on which field to group. There is
no method that looks like it does so on the SolrQuery object..

Ideas anyone ?

thanks,
Omri

Hi Omri,

SOLR-2637 was concerned with adding grouped response parsing. There is no
convenience method for grouping, but you can use the normal
SolrQuery#set(...) methods to enable grouping.
The following code should enable grouping via SolrJ api:
SolrQuery query = new SolrQuery();
query.set(GroupParams.GROUP, true);
query.set(GroupParams.GROUP_FIELD, "your_field");
