Question

I am using Result Grouping into the SOLR. How can i get the total number of results? By result I mean the count of grouped data.

For example:

I searched with 2 email addresses (“[e-mail]” OR “[e-mail]”). I got 2 results in the result set. There is numFound attribute in the result node which shows the email address “[e-mail]” matched 16 times and the email address “[e-mail]” matched 28 times. There is a matches attribute which shows the total number of matches (16 + 28 = 44). But i want to know the total number of result set which is 2 (1 for “[e-mail]” + 1 for “[e-mail]”). How can i get that?

Answer 1

For the number of groups use the groups.ngroups request parameter which will give you the group count.

Documentation :-

group.ngroups
true/false
If true, includes the number of groups that have matched the query. Default is false.
