Query Suggestions and Special Characters

Hi there. I have created and configured an Elasticsearch Index-based App Search Engine that has a char_filter to not strip $, *, and / characters as they are important to my business. My search queries work great, but Query Suggestions strip these characters (ex. query suggestion term of $20 returns results for 20). Does anyone know a way around this so that these characters are not ignored in the Query Suggestions? I'm willing to convert my Query Suggestions to native Elasticsearch if necessary.
