Hello
Have you ever checked the right formats expect by Joda date parser?

Of course.
And I'd like to use "basic\_date\_time" format. It looks like
this: yyyyMMdd’T’HHmmss.SSSZ
And I configured "basic\_date\_time" as a default format, what doesn't work.

I can confirm that this looks broken. Please open an issue
demonstrating the problem (and remove the dynamic mapping, it is still
broken without that)

This happens because there is a basic check to see if something is a date by looking for :, -, and / in the string before trying to parse it. Otherwise, is 20120101 a numeric number or a date? I guess we can improve that to also look for T, and if its there, try and parse.
