display text analytics sentiment score
Is it possible to display the avg score of the sentiment in facet?
Facets support performing aggregate operations on numeric fields, for each value that is displayed (of another field). In the current release we have nothing OOTB to display an aggregate for all the results (instead of per field value).
Still, I already had a similar need, so I finally took some time to add a stock component doing just that. I've put preliminary documentation here: https://developers.coveo.com/display/JsSearch/Aggregate+Component. It should land in the snapshot build in a few minutes (https://developers.coveo.com/display/JsSearch/Downloading) if you want to experiment with it.
