Creating an exposed filter with a global custom text field

Us an or group and add the four individual fields

Under the hood this maps to SQL OR conditons

I'm sorry,

Could you specify the steps about how I can create? I don't achieve to find the options on the view.

Exposed filters can only search in 1 field at a time (with the exception of the Combined field filter but that only works for text fields normally, but if you want to search on the exact content of your date fields it might work)

If you are using something like Search API you could try using an Aggregated field or if you can write custom code, you could try writing a Computed base field that grabs all the data you need and then searching on that Computed base field.

But with just Drupal core, this can't be done like this.
