> 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!
