Markus Jelsma commented on SOLR-4280:
-------------------------------------
Hello [~jdyer] - this sounds very good. However, an addition to this feature
would be the option to also choose which filter the fraction operates on. I
have seen some strange results when drilling deeper using more and more
restrictive filters.
It was originally meant to use maxResultsForSuggest in a multi-tenant index.
The current maxResultsForSuggest is not suitable for clients having a very
large index and clients having a small index.
How about an optional spellcheck.maxResultsForSuggest.fq=field:value. If the
user specifies this, the patch won't need to find the most restrictive filter.

> 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.
> Spun off from SOLR-4278.
