Suggester only returning on suggestion

["Kien, Theo" <Th...@bis.org.INVALID>]

Dear Solr user community,

I have started to use the Solr 8.9 suggester. The definition is as follows:

{
   "searchComponent":{
      "suggest_test":{
         "name":"suggest_test",
         "class":"solr.SuggestComponent",
         "suggester":{
            "name":"combinedSuggester",
            "lookupImpl":"BlendedInfixLookupFactory",
            "indexPath":"/var/solr/sprint2/suggester",
            "dictionaryImpl":"DocumentDictionaryFactory",
            "field":"COMBINED",
            "suggestAnalyzerFieldType":"text_general",
            "buildOnStartup":"false",
            "buildOnCommit":"false"
         }
      }
   },
   "requestHandler":{
      "/suggest":{
         "name":"/suggest",
         "class":"solr.SearchHandler",
         "startup":"lazy",
         "defaults":{
            "suggest":"true",
            "suggest.count":"10",
            "suggest.dictionary":"combinedSuggester"
         },
         "components":[
            "suggest_test"
         ]
      }
   }
}

When I tested this on a relatively small set of documents, it was working as expected.
For example, when requesting "suggest?q=south" it would return "south africa" and "south korea" as suggestions.
Now, on a different core with more documents, the same query returns "south africa", but "suggest?q=south k" still return "south korea".

Does anybody have an idea why this is the case and how I can debug the behaviour of the suggester?

Thanks in advance.
Best regards
Theo Kien
