> Hi,
> Unless I'm missing something it seems that there is a problem with group.offset in SolrCloud. For the example cloud Solr and the example data take a look at the following two queries:
> {noformat}
> http://localhost:8983/solr/gettingstarted/select?q=*:*&sort=id+desc&fl=id&group=true&group.query=cat:electronics&group.query=cat:connector&rows=5&group.limit=0&group.offset=0&wt=json&indent=on
> {noformat}
> And:
> {noformat}
> http://localhost:8983/solr/gettingstarted/select?q=*:*&sort=id+desc&fl=id&group=true&group.query=cat:electronics&group.query=cat:connector&rows=5&group.limit=0&group.offset=4&wt=json&indent=on
> {noformat}
> The response for the first query looks as follows:
> {noformat}
> {
> "responseHeader":{
> "status":0,
> "QTime":8,
> "params":{
> "q":"*:*",
> "indent":"on",
> "fl":"id",
> "group.limit":"0",
> "sort":"id desc",
> "group.offset":"0",
> "group.query":["cat:electronics",
> "cat:connector"],
> "rows":"5",
> "wt":"json",
> "group":"true"}},
> "grouped":{
> "cat:connector":{
> "matches":32,
> "doclist":{"numFound":2,"start":0,"docs":[
> {
> "id":"IW-02"},
> {
> "id":"F8V7067-APL-KIT"}]
> }},
> "cat:electronics":{
> "matches":32,
> "doclist":{"numFound":12,"start":0,"docs":[
> {
> "id":"VS1GB400C3"},
> {
> "id":"VDBDB1A16"},
> {
> "id":"TWINX2048-3200PRO"},
> {
> "id":"SP2514N"},
> {
> "id":"MA147LL/A"}]
> }}}}
> {noformat}
> And the response to the second query looks as follows:
> {noformat}
> {
> "responseHeader":{
> "status":0,
> "QTime":10,
> "params":{
> "q":"*:*",
> "indent":"on",
> "fl":"id",
> "group.limit":"0",
> "sort":"id desc",
> "group.offset":"4",
> "group.query":["cat:electronics",
> "cat:connector"],
> "rows":"5",
> "wt":"json",
> "group":"true"}},
> "grouped":{
> "cat:connector":{
> "matches":32,
> "doclist":{"numFound":2,"start":4,"docs":[
> {
> "id":"IW-02"},
> {
> "id":"F8V7067-APL-KIT"}]
> }},
> "cat:electronics":{
> "matches":32,
> "doclist":{"numFound":12,"start":4,"docs":[
> {
> "id":"VS1GB400C3"},
> {
> "id":"VDBDB1A16"},
> {
> "id":"TWINX2048-3200PRO"},
> {
> "id":"SP2514N"},
> {
> "id":"MA147LL/A"}]
> }}}}
> {noformat}
> You can see that the second query has group.offset=4 and even the header states that the start is set to 4, but the documents are still the same as the group.offset was set to 0.
> If this something I'm missing or we have a bug?
