You probably should adjust your matching, without matching set eg. to past or future you are searching for the records with exact same date and time. 

Thanks for your reply Klas!

I tried this, but it does not work.

may be it is because in DB the value is stored in Y-m-d format and I am trying to use d-m-Y.

I will update if changing it works.

Calendar field should automatically transform the date to the right format. First step with not-workable searches is always to turn on debugging in the search type so you can see what query is being run.

Hi Klas,

Thanks for your support!

Actually I am creating a simple epaper system with a list of epapers linked with the detail view.

The user must be able to search the epaper with the exact date so I can't use matching past or future.

I am geting this error now:

Would be very nice if you could pinpoint the cause of this error as it appears for people from time to time and it very hard to help if we don't know how to reproduce it.
