You cannot use 100% because, as you say, 1 is intepreted as "1 document". But you can do something like 99.99999% .

I'd already tried several values for maxQueryFrequency, but apparently without properly understanding it. I was confused by the line "A lower threshold is better for small indexes" when in fact I need a high value like 0.99, so every term returns suggestions. (Is it possible to set it to 100%? Because 1 gets interpreted as an absolute value.)
