What?!?! You want them grouped but not grouped together?? What on earth does
that mean?! I mean, either they are included or they are not. All results
will be in some group, so where exactly do you want these "not to be grouped
together" documents to be grouped? In any case, please clarify what your
expectations really are.

Subject: Re: Solr Grouping and empty fields
Thank you Johannes, but I want the documents having the field empty to
be included in the results, just not to be grouped together, and if I
understood your solution correctly, it will simply remove those
documents from the results (Note : The field values are very variable
and unknown to me).

Hi Oussama,
If you have only a few distinct, unchanging values in the field that you
group upon, you could implement a FilterQuery (query parameter "fq") and
add it to the query, allowing all valid values, but not an empty field.
For example:
fq=my_grouping_string_field:( value_a OR value_b OR value_c OR value_d )
If you use SOLR 4.x, you should be able to group upon an integer field,
allowing a range filter:
(I still work with 3.6 which can only group on string fields, so i didnt
test this one)
fq=my_grouping_integer_field:[1 TO *]

Betreff: Solr Grouping and empty fields
Hi,
I need to group some results in solr based on a field, but I don't want
documents having that field empty to be grouped together, does anyone
know how to achieve that ?
