NGram index creation/usage example in the documentation

[MiklosPathy]

Is your feature request related to a problem? Please describe.
Actually, yes. I would like to create such an index on a filed, but my knowledge is limited to do it with the .NET API.

Describe the solution you'd like
A section in the documentation with this particular example, maybe more advanced examples.

Describe alternatives you've considered
Tried to search for something like this. I found an issue similar to this on Stack Overflow, but the guy gave up, and created his index with web api, and direct json. ChatGPT hallucinates something based on the old 7.x API, but it is unusable with 8.x. The closest i was, to create an analyser, but i was not able to bind it to a field.

Additional context
Nothing special, just a code snippet. For example: here is a type: Document, it has a field DocText, this is how you create the index, with NGram analyser, this is how you use it for searching.

Hey @MiklosPathy, could you please post the JSON request for creating the desired index?

Unfortunately, I am not on that level in ElasticSearch. Any example would do, I (and probably many other) will figure out the rest.
