Issei Nishigata commented on SOLR-10010:
----------------------------------------
I guess this is causing
org.apache.lucene.analysis.synonym.SynonymFilterFactory#loadSynonyms doesn't
set tokenizerFactory.minGramSize="2", tokenizerFactory.maxGramSize="2" when
calling loader.inform() ( => constructor of
"org.apache.solr.schema.IndexSchema")
(tokArgs is empty)
> NGramTokenizer with SynonymFilterFacory doesn't work properly when using
> Managed-Schema
