Thank you @yetanothertw, this already looks really good!I

I've left a few suggestions for your consideration. Many of them are related to the new search tutorial we're adding and how it might change the role of the Get started page, as well as the semantic field type and the multimodal search page/tutorial.

@yetanothertw -- following from our conversation just now: the maximum data size for a VDB project is 1TB, so we should have that in the docs.

Is this limit adjustable @dustincoates ? Can we say that it can be increased by request (via support)?

We can say to contact sales.

Here's why I'm asking, this is what it currently looks like on the Compare Elastic Cloud Hosted and Serverless page:

So I was aiming for parity with the other two entries, that are described as adjustable. If it's not adjustable, that's okay too @dustincoates

[dustincoates]

@yetanothertw in that case, I would mark it as not adjustable
