Testing

Unfortunately, the search functionality may not work in the demo link. Payment is required to enable such a service, which at the moment is not really necessary. You can run the application in your local machine to test it out.

• Clone this repo:

  $ git clone git@github.com:GitauHarrison/search-functionality-in-flask.git

• Change directory to the cloned repo:

  $ cd search-functionality-in-flask

• Create and activate a virtual environment:

  $ mkvirtualenv venv # I am using virtualenvwrapper

• Install project dependencies in your active virtual environment:

  (venv)$ pip3 install -r requirements.txt

• Update environment variables:

  (venv)$ cp .env-template .env

• Configure elasticsearch (see reference section below)

• Run your Flask server:

  (venv) flask run

• Paste the localhost URL into your favorite browser to access the GUI application

• Use the search form to query for data
