When trying to implement a basic form I get the following error message: werkzeug.routing.BuildError: Could not build url for endpoint 'finder.search'. Did you mean 'finder.static' instead?, the index.html page does not even load because of this error.

You cannot use the url_for directly in the template, Jinja cannot process it. You should pass it as a variable to the render_template function and use that variable name in the jinja block.
Example:
return render_template("index.html", form_action_url=url_for('finder.search'))
and the form's action will be:
<form action="{{ form_action_url }}" method="post">
<label for="query">Query:</label><br>
<input type="text" id="query" name="query"><br>
<input type="submit">
</form>
