Maciej Niemczyk created SOLR-5191:
-------------------------------------
Summary: spellcheck.maxResultsForSuggest is ignored
Key: SOLR-5191
URL: https://issues.apache.org/jira/browse/SOLR-5191
Project: Solr
Issue Type: Bug
Components: spellchecker
Affects Versions: 4.3
Environment: Mac Os X, java 7 version "1.7.0_21"
Reporter: Maciej Niemczyk
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):
{code}
{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}}
{code}
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:
{code}
_spellResponse:
correctlySpelled = false
collations = null
suggestions = ArrayList (size = 0)
suggestionMap = LinkedHashMap (size = 0)
{code}
My configuration is very close to the default provided one.
