Hi,
I need a feature which is well explained from Mr Goll at this site **
So, it then would be nice to do sth. like:
facet.stats=sum(fieldX)&facet.stats.sort=fieldX
And the output (sorted against the sum-output) can look sth. like this:
<lst name="facet_counts">
<lst name="facet_fields">
<lst name="tag">
<int name="jobs" fieldX="14700">767</int>
<int name="video" fieldX="13700">892</int>
Is there something similar or was this answered from Hoss at the lucene
revolution? If not I'll open a JIRA issue ...
BTW: is the work from
http://www.cs.cmu.edu/~ddash/papers/facets-cikm.pdf contributed back to
solr?
Regards,
Peter.

Quoting his question in case the site goes offline:
Hi Chris,
Usually a facet search returns the document count for the
unique values in the facet field. Is there a way to
return a weighted facet count based on a user-defined function (sum,
product, etc.) of another field?
Here is a sum example. Assume we have the following
4 documents with 3 fields
ID facet_field weight_field
1 solr 0.4
2 lucene 0.3
3 lucene 0.1
4 lucene 0.2
Is there a way to return
solr 0.4
lucene 0.6
instead of
solr 1
lucene 3
Given the facet_field contains multiple values
ID facet_field weight_field
1 solr lucene 0.2
2 lucene 0.3
3 solr lucene 0.1
4 lucene 0.2
Is there a way to return
solr 0.3
lucene 0.8
instead of
solr 2
lucene 4
Thanks,
Johannes
