Erick Erickson created SOLR-13175:
-------------------------------------
Summary: Rollup does not roll up NULL values.
Key: SOLR-13175
URL: https://issues.apache.org/jira/browse/SOLR-13175
Project: Solr
Issue Type: Bug
Security Level: Public (Default Security Level. Issues are Public)
Reporter: Erick Erickson
Steps to reproduce:
- Create a 2-shard collection for sample tech products configs and index all
the example documents to it (I always use "eoe" as my collection ;) )
- Submit this expression:
{code{
rollup(
search(eoe, q="*:*", fl="popularity", qt="/export", sort="popularity
asc"),
over="popularity",count(*))
{code}
Results: Note that the "NULL" bucket is repeated, presumably once from each
shard. The rest of the rollup is aggregated appropriately.
{code}
{
"result-set": {
"docs": [
{
"count(*)": 15,
"popularity": "NULL"
},
{
"count(*)": 1,
"popularity": 0
},
{
"count(*)": 2,
"popularity": "NULL"
},
{
"count(*)": 2,
"popularity": 1
},
etc.
{code}
