Web service to autocomplete diagnoses

Files:

• Trie.py: Implementation of Trie data structure for prefix tree
• diagnosis_search.py: Flask app with API for autocomplete and updating/storing query with selected diagnosis

Setup

Create a new virtualenv named 'hd', activate it, and install requirements:

virtualenv hd

. hd/bin/activate

pip install -r requirements.txt

Run diagnosis_search.py to start web service:

chmod a+x diagnosis_search.py

./diagnosis_search.py

Now the webservice is running on localhost:5000/
