sql closest matching record from a query NodeJS API

Working on an API that returns information my db has regarding an address The API url:

/api/allinfo?street_number=&street_name=&state=&zipcode=

Problem is this will only return a row if the spelling EXACTLY matches the spelling in my DB. How do I handle the event they misspell the street_name or give the wrong street_number for example, that it will return the CLOSEST match

I currently have

// Provide the user all the information in the GNAF dataset pertaining to 
the given address.
app.get("/api/allinfo", function (req, res) {

 sql.connect(dbConfig, function (err) {

     const request = new sql.Request();
     query = `SELECT *FROM Addresses
                WHERE zipcode= @zipcode AND street_name 
        = @street_name AND state_abbreviation = @state_abbreviation
                AND street_number = @street_number`;

    request.query(query, (err, result) => {
            res.send(result);
        sql.close();
    })
});
});
