Change date field until minute to zero for group by

[suhyunjeon]

I got date fields like this.

{
   date:2013-11-01T16:14:55.372Z,
   latency:1
},
{
   date:2013-11-01T16:14:00.372Z,
   latency:6
},
{
   date:013-11-01T16:15:17.496Z,
   latency:3
}

I want to see the count to group by the date field(until minutes)  like
that.

{
   date:2013-11-01T16:14:55.372Z,
   latency:6
},
{
   date:013-11-01T16:15:17.496Z,
   latency:3
}

So I have to change the date field format to Raw Query Parameters. 

How do I do? Help me please. It didn't work.

My Raw Query Parameters :
group=truegroup.field=log_ts_tdtgroup.facet=truegroup.func=rint(div(ms(log_ts_tdt),mul(24,mul(60,mul(60,1000)

Can I select dummy field(for count) from solr?

[suhyunjeon]

I want to show cumulative graph from banana framework(SiLK).
https://docs.lucidworks.com/display/SiLK/Banana

There is no cumulative graph so  I want to select count(*) from solr
collection like dummy field.

So then I am going to sum the field(count(*)) and show histogram graph.
Do you have idea? 

It does not work like this. (q = *:count(*))
