Search in index section

[yottanami]

Adding a simple dynamic search box for filtering index items.
For example, it checks if there is a date time field, it shows from/to date search field.
By default, all columns can be searchable but the list of searchable items can be customized in index dashboard DSL.

The filter branch can help to handle it.
