Subject Re: Fast autocomplete for large dataset

Not really. There's no need to use ngrams as the article suggests if the
terms component does what you need. Which is why I asked you about what
autocomplete means in your context. Which you have not clarified. Have you
even looked at terms component?  Especially the terms.prefix option?

Terms component has it's limitations, but performance isn't one of them.
The suggesters mentioned in the article have other limitations. It's really
useless to discuss those limitations, though, until the problem you're
trying to solve is clearly stated.
