[VuFind-General] Autocomplete on subjects/MARC 650a

[<in...@fl...>]

I'd like to get results for autocomplete _only_ from subjects (MARC 650a).

I did try to configure local/config/vufind/searches.ini, but 
autocomplete continues to suggest complete (article) titles.


What do I miss? Thanks for any pointers.

This my configuration:

[Autocomplete]
enabled = true
[Autocomplete_Types]
default_handler = Solr

[Autocomplete_Types]
Subject = "Solr:Subject:topic"
;Title = "Solr:Title"
;JournalTitle = "Solr:JournalTitle"
;Author = "Solr:Author:author,author2"
;CallNumber = "SolrCN"
;ISN = "Solr:ISN:isbn,issn"
;tag = "Tag"

I also did edit local/config/vufind/searchspecs.yaml to fit an article 
based index only and did a reindex:

JournalTitle:
   DismaxFields:
     - container_title^250

   QueryFields:
     container_title:
       - [onephrase, 275]
       - [and, 225]
   FilterQuery: "format:Journal OR format:Article"
