yep - I am trying to do it the other way around. And the reason is like everybody we are trying to keep our storage costs down. Searching for ten extra name variations has no real impact at search time. Storing millions of ngramed names has a financial cost.
Going back to my question. I actually want the terms split on whitespace so I have added token_char back in (cause the order of terms is not important in my scenario). I pretty much understand how it works now.
What would be ideal if you could search for term A (and its edge-ngrams) AND term B(and its edge-ngrams). Is this possible?
