now can i create a refinable managed property that combine the values of both fields to generate a date & time field? so i can search, filter and sort items based on this refianble value?

so if i have a combination of the 2 columns as follow:-

22 August 2024 9:00 pm

22 August 2023 11:00 am

and i sort them descending then

22 August 2024 9:00 pm

should be shown before

22 August 2023 11:00 am

is this possible? to manage inside sharepoint search?

Answer 1

Per my test, it is not possible to create a refinable managed property that combine the values of both fields to generate as a date & time field.

In the SharePoint search, you could use refinable managed property equal to a value to filter search results. It can be a value from one filed but cannot a combined value form two fields.

So, as a workaround, you could use two refinable managed properties to filter search results or create a date and time field as refinable managed property to filter search results.
