Solr Query Parameter LIKE

Question

I want to search through my content using Solr. My question is, is there a possibility to search for a text, which contains a certain character sequence?

Example: I have a text like "This is my Regitrationmail" I want a query for the search of "registration" or "mail" or even "Registrationm" etc. etc. Also the query should match if the content or the title match the query.

this is my current query:

q=text:registration~20

Thanks for your help!
