> In a view query, if both group and group_level is specified the last one specified overrides any of the previous "group" or "group_level" parameters.
> Example:
> Create a db (db1), at least one document, a design doc (des1) that looks like:
> {code:javascript}
> {
>    "views": { 
>          "v1" : { "map": "function(d){
>                                      emit([1,1],1); 
>                                      emit([1,1],10);
>                                      emit([1,2],100); 
>                                      emit([1,2],1000); 
>                                      emit([2,2],10000);
>                                    }" , 
>                      "reduce":"_sum" 
>      } 
> }
> {code}
> Then these queries show the problem:
> {code}
> $ http "$DB1/db1/_design/des1/_view/v1?group_level=1&group=true"
> {"rows":[
> {"key":[1,1],"value":11},
> {"key":[1,2],"value":1100},
> {"key":[2,2],"value":10000}
> ]}
> {code}
> But users might expect group_level=1 results to show or a 400 request invalid.
> Specifying group_level=1 after group=true make group_level=1 take effect:
> {code}
> $ http "$DB1/db1/_design/des1/_view/v1?group_level=1&group=true&group_level=1"
> {"rows":[
> {"key":[1],"value":1111},
> {"key":[2],"value":10000}
> ]}
> {code}
