I want to create a histogramfacet based on when the page or file was created. Making a histogram facet with the published date was easy, but the created date is not part of ISearchContent.
I think you can do something like this:
var result =
.HistogramFacetFor(x => ((IChangeTrackable) x).Created, DateInterval.Year)
var facets = result.HistogramFacetFor<IChangeTrackable>(x => x.Created);
Works like a charm. Thanks!
