In your search method, if the request method was POST, you are trying
to retrieve submitted data via key 'search_string'. However, if you
look at your HTML form, there does not seem to be any kind of input
field called 'search_string'.

Try adding name="search_string" parameter to the input element, for
example:

<input type="text" name="search_string" class="form-control" placeholder="Search Article Text">

On a side-note, why are you even using POST method for a search? I
_think_ that GET should be sufficient, and probably more correct thing
to use, unless your searches are actually altering data (which could be
considered a bad practice).

Best regards
