Description

Given a request with spellcheck.maxResultsForSuggest = 1 the response should has spellchecked = true if there are some hits according to SOLR-3457 and SOLR-2585.

request (taken from response header):

{status=0,QTime=28,params={spellcheck=true,facet=true,sort=sortDate desc,facet.limit=15,spellcheck.q=Microsoft,facet.range=updatedAt,facet.range.gap=+1YEAR,hl=true,version=2,facet.range.start=NOW/YEAR-10YEARS,facet.field=[categories, language],fq=[-documentType:userSearch, -status:deleted],spellcheck.build=true,hl.fragsize=150,facet.mincount=1,spellcheck.maxResultsForSuggest=1,spellcheck.extendedResults=false,qf=title^8 categories^3 content all^0.5,facet.range.end=NOW/YEAR+1YEAR,hl.fl=title,content,teaser,wt=javabin,spellcheck.collate=true,defType=edismax,spellcheck.onlyMorePopular=true,rows=10,start=0,q=Microsoft}}

The HitCount is: response.getResults().getNumFound() = 5541
And by the way its also the same Response with arbitrary spellcheck.maxResultsForSuggest, even beyond 5541.

Spellcheck Response:

_spellResponse:
  correctlySpelled = false
  collations = null
  suggestions = ArrayList (size = 0)
  suggestionMap = LinkedHashMap (size = 0)

My configuration is very close to the default provided one.
