Question by Dan Cruickshank, Feb 23, 2016 11:59 AM

Complex Sorting - Date Ranges

We have a scenario where we have a items with dates and date ranges, think of them as events.

  • A) Feb 1 - Feb 28 (End Date: Feb 28)
  • B) Feb 27 (End Date: Feb 27)
  • C) Feb 15 - March 15 (End Date: March 15)
  • D) Feb 10 - March 30 (End Date: March 30)
  • E) Jan - March 31

Sorting by "end date" gives us the following order: B,A,C,D, E

With today being Feb 23, the true order should be. A, C, D, E, B

Basically, if an event is currently happening we should be sorting by todays date, not the end date of the shows. End date should be the secondary sort.

I think we need to generate an on-the-fly field that returns in the current date if the show is active and the end date if the show is not yet active. In Sitecore the items have a start and end date and but aren't reindexed everyday for generate a "todays date" as a server side computed field. I suppose we could write an agent to do so, but I'm wondering if we could solve this problem in Coveo. :)

Any thoughts on a solution for this?

I'm aware of query functions:

But that looks pretty-pretty-dark!

Hi Dan,

This is a very good question. Here's my attempt at it. Let's assume some things:

  • Events that are finished aren't part of the search results (query filter @enddate>=today)
  • Events that are one day long only have the same start date as the end date (may be done with PostIemProcessingPipeline processor)

I would use the sortCriteria property of the JS UI queryBuilder and set 2 sort fields as supported since the June 2015 release (see sortCriteria) like this:

args.queryBuilder.sortCriteria = '@startdate ascending, @enddate ascending';

So for any 2 events with the same start date, the one ending earliest will be first.

Tell me if this works for you,

Discard this answer as it doesn't solve your problem of sorting the events by the number of remaining days until end. I'll sleep on it and try to get something better.
