Searching for document file names

When I work on OPO official docs, I have to upload the corresponding complaint doc into the page. Each document is identified by a unique ICMS number. Since that number is only useful for internal purposes, we end up giving the document, once uploaded into joplin, a generic title- one that is often shared by several different documents. The "title" column in the image below is the generic name and the "file" is the original title of the file, which is the ICMS number.


The problem with this is that it becomes very tedious to search documents when wanting to add a document or make any edits. Sometimes I have to scroll through multiple pages within the document search to get to my document. Is there a way to expand search to the "file" column as well?
