your /sugest searchhandler defines "spellcheck.dictionary" twice : 1 time title_autocomplete field , 1 time models field. aside fact don't know how solr behaves when having same key specified twice, don't see models_autocomplete field specified anywhere in config, neither default searches or sugest components utilize it's dictionary query it.

edit :

switch model models_autocomplete , see if works . consider switching default qparser edismax , specifying multiple search fields. of course of study assuming autosugest requests utilize /sugest url
