Markus Jelsma updated SOLR-4280:
--------------------------------
Attachment: SOLR-4280-trunk-1.patch
Patch for trunk introducing a spellcheck.percentageResultsForSuggest. It uses
the filterCache to check the maximum number of possible results so whether a
term is misspelled relies on how large the maximum result set is and the value
for this parameter.
Since the filterCache cannot be retrieved from SolrIndexSearcher.getCache() at
this moment you'll have to hack into it and have it add the filterCache to the
cacheMap somewhere in the constructor.
{code}
cacheMap.put(filterCache.name(), filterCache);
{code}
> spellcheck.maxResultsForSuggest based on filter query results

>
> 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.
