James Dyer updated SOLR-4280:
-----------------------------
Attachment: SOLR-4280.patch
Here is an updated patch for Trunk. I've included unit tests and changed
javadoc to reflect the added functionality. I've also modified how this gets
triggered. Rather than introduce a new request parameter, the user passes in
"spellcheck.maxResultsForSuggest" as a fractional percent, between 0 and 1. So
if the user wants no more than 5% of the most-selective filter's results to be
the maximum results to trigger suggestions, they would specify
"spellcheck.maxResultsForSuggest=.05". If, for instance, the most-selective
filter returns (by itself) 100 documents, then the effective maximum number of
hits we will return without triggering spelling suggestions is 5.
[~markus17] does this all sound right to you? Is this still a feature you want
and would be interested in seeing committed?

> 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.
