SOLR 6.4.1. It seems stubbornly case sensitive, how to make case insensitive?

I tried everything under the sun (well, after all, it's called solr) to make solr Suggest case insensitivity, but it stubbornly continues to be case sensitive.

This returns the Mexican sentence:

http://localhost:8983/solr/mycollection/autocomplete?suggest.q=Mex

This returns 0 results:

http://localhost:8983/solr/mycollection/autocomplete?suggest.q=Mex

To conduct additional diagnostics, I tried to search in the lowercase / select in the field of my sentences, in which documents containing "Mexican" appeared successfully:

http://localhost:8983/solr/mycollection/select?q=suggestions:mex*

But there is no such luck using lowercase letters with the site. As if mine <filter class="solr.LowerCaseFilterFactory"/>doesn't work when used by a developer site.
