Web Forms / C# / How to read a binary file from SQL database

I have a request to search files in the database for a specific text criteria.  Is there a way to do this with it being in the database and binary?   OR do I need to also save the file on the file system and then there is a way to do it that way. So basically if they upload a document called: myTest.doc and in that document there is a part of a sentence that says "This is a test to read a file via a text search". Then they search for "This is a test", via a UI, then it should return me that document so they can open etc.
