Startup Idea: Efficient Multi-File Type Search Engine Software for Retail

Startup idea to develop a software capable of searching across multiple file types (notepad, excel, access, doc, paint, etc.), promptly and more effectively than current solutions in a retail setting. The software will aid in customer data handling and report searching, with quicker and more precise results than typical Windows 10 native file search or similar solutions like DocFetcher.

I work for a small retail client. A big pain I have is entering data about customers and writing reports and then SEARCHING for this data.

Reports and customer documents are saved in notepad, excel, access, doc, paint, and many other file types. It is a pain to search them all.

I would like a software that searches across ALL documents and files quickly. The only way I have now is the Windows 10 native file search, but it is much to slow and does not get all the stuff I want. I found DocFetcher. It is similar to what I want, but does not contain all the misc. file types I need to search.
