If you turn on facets in your query (facet=true&facet.field=) then 
you'll get back all of the distinct values, though might have to play with 
other settings (e.g. facet.limit=-1) to get the results you need.

SOLR-2242 can do it.

I could get this number by using

 group.ngroups=true&group.limit=0

 but doing grouping for this seems like an overkill

 Would you advise using JIRA SOLR-1814 ?

 Simple question: I want to know how many distinct elements I have in a field 
and these verify a query. Do you know if there's a way to do it today in 3.4. I 
saw SOLR-1814 and SOLR-2242. SOLR-1814 seems fairly easy to use. What do you 
think ? Thank you

Distinct elements in a field

Simple question: I want to know how many distinct elements I have in a field 
and these verify a query. Do you know if there's a way to do it today in 3.4.

 I saw SOLR-1814 and SOLR-2242.

 SOLR-1814 seems fairly easy to use. What do you think ? Thank you
