Gary Yang created SOLR-7828:
-------------------------------
Summary: add a new facet function to pick one result's value
Key: SOLR-7828
URL: https://issues.apache.org/jira/browse/SOLR-7828
Project: Solr
Issue Type: New Feature
Components: faceting
Affects Versions: 5x
Reporter: Gary Yang
The facet functions and analytics working great, especially with json API !
As a developer, I would like a facet function to get a field value from one
record from a group, please see this facet query:
{
"schema": {
"slide_id": {
"type": "long"
},
"slide_name": {
"type": "string"
},
"slide_create_time": {
"type": "timestamp"
}
},
"facet.query": {
"slide_viewed": {
"type": "terms",
"field": "slide_id",
"facet": {
"avg_viewed_time": "avg(slide_viewed_time)",
"created_time": "max(slide_create_time)",
"slide_name":
"*{color:red}ANY_FIRST_LAST_OR_FILTER{color}*(slide_name)"
}
},
"total": {
"type": "query",
"q": "*:*",
"facet": {
"slide_num": "unique(slide_id)"
}
}
}
}
when grouping by slide_id, I would love to have the a function that can pick a
slide name from each group of slides with the same slide_id.
thanks!
