Can't search by specific date

[sshcli]

Steps to reproduce the issue

1. Go to example.com/forum/search
2. Try to search all the posts created on April 29 2016 (Example date, you can use another)

Expected result

You should be able to see only the posts created on April 29 2016

Actual result

There is no option in the drop down list to choose a specific date

System information (as much as possible)

Joomla version: 3.6.2
Kunena version: 5.0.1
Php version: 7.0.10
Database version: 5.6.31

If we want to search at a specific date, i think we can add a datepicker to choose the date

[sshcli]

A datepicker seems to be a good idea.
Whatever you do will be fine.
