Description

spellcheck.maxResultsForSuggest takes a fixed number but ideally should be able to take a ratio and calculate that against the maximum number of results the filter queries return.

At least in our case this would certainly add a lot of value. >99% of our end-users search within one or more filters of which one is always unique. The number of documents for each of those unique filters varies significantly ranging from 300 to 3.000.000 documents in which they search. The maxResultsForSuggest is set to a reasonable low value so it kind of works fine but sometimes leads to undesired suggestions for a large subcorpus that has more misspellings.
