/**
 * Determines what is done on the view once it has been created
 *
 * @param view                  The current activity
 * @param savedInstanceState    The state of the screen before interrupts appear, such as leaving the app

         * Listens for changes in the searchview
         * OnQueryTextChange invokes whenever the user types, while on the other hand
         * OnQueryTextSubmit invokes only when the user submits the keywords.
         *
         * There are 3 scenarios:
         *      1. if(sentence.length == 0)  and if(searchController.getKeywords().isEmpty() == true)
         *          sentence is the words the user types in.
         *
         *          These conditions check if the user entered in previous search words,
         *          if not then nothing happens since all tasks are shown to begin with
         *
         *      2. if(sentence.length == 0)  and if(searchController.getKeywords().isEmpty() == false)
         *
         *          These conditions are for when the user had previously searched for keywords and now wants
         *          to see all the available tasks. It first clears the listview then does a search returning all
         *          available tasks.
         *
         *      3. The last condition is when the user is searching for tasks by entering in keyword(s).
         *          This clears the listview and then proceeds to make a search request using the keyword(s)
         *          as a parameter. It then returns the tasks containing the keywords in the descriptions.
         *
