Antoine Le Floc'h commented on SOLR-2242:
-----------------------------------------


People who need to be back-compat won't be able to use {code} &facet.numTerms=true {code}. Isn't it fair ?

About the distribution issue, maybe the distinct counter could be displayed per shard, something like:
{code}
<lst name="facet_fields">
  <lst name="shop_id">
    <lst name="numTerms"> 
      <int ip="192.168.0.100">58</int>
      <int ip="192.168.0.101">158</int>
    </lst>
    <lst name="counts">
      <int name="28013756">7032406</int>
      <int name="28009589">3616625</int>
      <int name="976">3497825</int>
      <int name="635">1398780</int>
      <int name="28021713">440118</int>
    </lst>
  </lst>
</lst>
{code}
Like this, people who don't use shards are happy, and people who do, can display what makes sense for them, waiting for better in the future. This would allow to move forward with this JIRA.

> When returning facet.field=<name of field> you will get a list of matches for distinct values. This is normal behavior. This patch tells you how many distinct values you have (# of rows). Use with limit=-1 and mincount=1.
> The feature is called "namedistinct". Here is an example:
> http://localhost:8983/solr/select?shards=localhost:8983/solr,localhost:7574/solr&indent=true&q=*:*&facet=true&facet.mincount=1&facet.numFacetTerms=2&facet.limit=-1&facet.field=price
> http://localhost:8983/solr/select?shards=localhost:8983/solr,localhost:7574/solr&indent=true&q=*:*&facet=true&facet.mincount=1&facet.numFacetTerms=0&facet.limit=-1&facet.field=price
> http://localhost:8983/solr/select?shards=localhost:8983/solr,localhost:7574/solr&indent=true&q=*:*&facet=true&facet.mincount=1&facet.numFacetTerms=1&facet.limit=-1&facet.field=price
> This currently only works on facet.field.
> {code}
> <lst name="facet_fields">
>   <lst name="price">
>     <int name="numFacetTerms">14</int>
>     <int name="0.0">3</int><int name="11.5">1</int><int name="19.95">1</int><int name="74.99">1</int><int name="92.0">1</int><int name="179.99">1</int><int name="185.0">1</int><int name="279.95">1</int><int name="329.95">1</int><int name="350.0">1</int><int name="399.0">1</int><int name="479.95">1</int><int name="649.99">1</int><int name="2199.0">1</int>
>   </lst>

> {code} 
> Several people use this to get the group.field count (the # of groups).
