The completion suggester uses payloads (which will presumably use extra space on disk) and specifies its own set of analyzers (presumably suggesting that the terms are analyzed a second time). Therefore I assume if I enable the completion suggester for a bunch of fields, it will use more disk space. Does anyone have any idea how much more? -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

Hey, be aware, that the completion suggester not only needs disk space, but also resides in memory (the secret of its speed). Thats why there is a stats API for completion stats. This is also the reason, that you should thrive for a minimum payload, as this can explode the size of the completion data tremendeously. That said, trying out and checking seems to be the most viable option.
