Search box for changing index pattern in the discover app is no longer searchable via name (aka custom pattern ID)

[jsermer]

Kibana version: 7.5.2

Elasticsearch version: 7.5.2

Server OS version: CentOS Linux release 7.4.1708 (Core)

Browser version: Chrome Version 80.0.3987.122 (Official Build) (64-bit)

Browser OS version: Mac OS 10.14.6

Original install method (e.g. download page, yum, from source, etc.): yum

Describe the bug: Previously (6.8.6), you could search the possible index patterns in the discover app via name and not just by searching for actual index pattern matching terms.

Steps to reproduce:

1. Create index pattern with a custom name
2. Open discover and attempt to search for the index pattern by the custom name

@cchaos or @kertal do you know if this functionality was intentionally removed when we swapped the index pattern selector to use EUI in #46347?

This was the previous functionality that @jsermer is referring to. Setting the kibana-* index pattern with a Custom index pattern ID of "custom id". Then using either "custom" or "kibana" will show the kibana-* index pattern as an option.

6.8.6 custom id is searchable

7.6.1 custom id is not searchable

Huh, I had no idea that index patterns had this feature. Seem like quite a hidden feature. I assume since Discover used Lens' component, and Lens (aka the builders of Lens, aka me) wasn't aware of this functionality it was never tested for support. I'd assume there needs to be extra functionality added to support custom pattern id's.

Would it ever make sense to display this custom pattern id next to the index-pattern in the list itself? Or maybe list it as it's own option? Seems oddly hidden when in the old UI, typing a custom id doesn't match the visual results.

[jsermer]

Specifically, our users find this feature useful if you have an index pattern referencing multiple different index names (networklogs-,applogs-) and you wanted to provide a 'custom' name (alllogs).

[nickofthyme]

@cchaos same, I never knew it existed and is definitely a hidden feature. The strange thing is that I don't see where the custom id is ever displayed beyond the creation of the index pattern. Seems like that would be nice to display to utilize this functionality.

@jsermer I can see how this would help with that.

[jsermer]

The only place I can see it displayed is in the URL or via the Kibana API

[nickofthyme]

Good to know.

[kertal]

I was also not aware of this feature, we could definitely display it in the list next to the name

Closing this because it's not planned to be resolved in the foreseeable future. It will be tracked in our Icebox and will be re-opened if our priorities change. Feel free to re-open if you think it should be melted sooner.
