SOLR terms autocomplete returns not all words

I have a problem with SOLR terms.

My query is

http://localhost:8080/solr/terms?terms=true&terms.lower.incl=false&indent=true&wt=json&terms.fl=a_dm_testo&terms.prefix=quel

Response from SOLR

{"responseHeader":{
    "status":0,
    "QTime":0},
  "terms":{
    "a_dm_testo":[
      "quell",1]}}

But this field in SOLR contains much more words with pre开发者_运维百科fix "quel":

quello - 2 quelle - 1 quella - 1 ....

I don`t understand what is wrong, can anybody help me?

Problem was with settings of schema.xml. When I rolled back to default "text_general" settings in schema.xml my problem was resolved.
