Problems creating a search engine

[SheeppOSU]

This is the only other form that I found that it might work in, if it doesn't work then I've got nothing else even after going through at least 10 various pages.

@app.route("/search", methods=["GET", "POST"])
def search():
    searchString = 'user'
    b = db.execute(f"SELECT * FROM books WHERE author LIKE %{searchString}%").fetchone()
    print(b)
    return render_template("search.html", anyVariableName=b)
