Sharepoint online modern search configuration

Hello, question about search in a modern site- I'd like the list search to focus on the file name in the library and few other metadata fields only and not the content inside the fields.

I created a new result source and in the query builder I'm trying the following query(listed below) but it not quite giving me the result. Do I need to configure anything else to get that going? Any other suggestion on what I could be missing here/doing wrong?

{searchTerms}(Title:"{SearchBoxQuery}*"OR Filename:"{SearchBoxQuery}"OR DocCode:"{SearchBoxQuery}")ANDContentTypeId:{'ContentTypeIDGoesHere'}
