Hello  
I have a bunch of dates to sort, this is the format I have:

```auto
2018-05-12 00:00pm GMT (always 00:00pm)
2021-04-01 1:17am GMT

```

If I try to ingest with no template, elasticsearch detects them as a string, but if I map them as a Date I get this error:  
`{"type"=>"illegal_argument_exception", "reason"=>"failed to parse date field [2020-08-22 00:00pm GMT] with format [strict_date_optional_time||epoch_millis]", "caused_by"=>{"type"=>"date_time_parse_exception", "reason"=>"Failed to parse with all enclosed parsers"}`

I've selected all options, always with the same result, as far as I know the date time string is valid, any idea?

You need to use "match" setting in date filter to provide all your date formats.

Thanks for your answer, but I have another question :S  
I'm reading about parsing string to date, but I must say its not so clear. But I've learned several things.  
Let's ask:  
I have two fields with dates like:

`2021-07-15 8:18 AM`

I'm trying with configs like:

```auto
      date {
        match => ["myField", "yyyy-mm-dd hh:mm"]
        target => "myField"
      }

```

I get no errrors, but "The indices which match this index pattern don't contain any time fields."  
If I try to set the date mapping, then, again, error parsing....

What I'm doin' wrong?

</div>

What contains [myField]? Just date or is it entire log?

Just the datetime with a format like "2021-07-15 8:18 AM"
