configuration

Flask configuration for this blueprint:

    from apies import apies_blueprint
    import elasticsearch

    app.register_blueprint(
        apies_blueprint(['path/to/datapackage.json', Package(), ...],
                        elasticsearch.Elasticsearch(...), 
                        'index-to-search-in', 
                        document_doctype='document',
                        dont_highlight=['fields', 'not.to', 'highlight']),
        url_prefix='/search/'
    )

local development

You can start a local development server by following these steps:

  1. Install Dependencies:

    a. Install Docker locally

    b. Install Python dependencies:

    $ pip install dataflows datapackage-pipelines-elasticsearch
    $ pip install -e .
    
  2. Go to the sample/ directory

  3. Start ElasticSearch locally:

    $ ./start_elasticsearch.sh
    

    This script will wait and poll the server until it's up and running. You can test it yourself by running:

    $ curl -s http://localhost:9200
     {
         "name" : "DTsRT6T",
         "cluster_name" : "elasticsearch",
         "cluster_uuid" : "QnLVHaOYTkmJZzkCG3Hong",
         "version" : {
             "number" : "5.5.2",
             "build_hash" : "b2f0c09",
             "build_date" : "2017-08-14T12:33:14.154Z",
             "build_snapshot" : false,
             "lucene_version" : "6.6.0"
         },
         "tagline" : "You Know, for Search"
     }
    
  4. Load data into the database

    $ python load_fixtures.py
    

    You can test that data was loaded:

    $ curl -s http://localhost:9200/jobs/_count?pretty
     {
         "count" : 3516,
         "_shards" : {
                 "total" : 5,
                 "successful" : 5,
                 "failed" : 0
         }
     }
    
  5. Start the sample server

    $ python server.py 
     * Serving Flask app "server" (lazy loading)
     * Environment: production
     WARNING: Do not use the development server in a production environment.
     Use a production WSGI server instead.
     * Debug mode: off
     * Running on http://127.0.0.1:5000/ (Press CTRL+C to quit)
    
  6. Now you can hit the server's endpoints, for example:

         $ curl -s 'localhost:5000/api/search/jobs?q=engineering&size=2' | jq
         127.0.0.1 - - [26/Jun/2019 10:45:31] "GET /api/search/jobs?q=engineering&size=2 HTTP/1.1" 200 -
         {
             "search_counts": {
                 "_current": {
                 "total_overall": 617
                 }
             },
             "search_results": [
                 {
                 "score": 18.812,
                 "source": {
                     "# Of Positions": "5",
                     "Additional Information": "TO BE APPOINTED TO ANY CIVIL <em>ENGINEERING</em> POSITION IN BRIDGES, CANDIDATES MUST POSSESS ONE YEAR OF CIVIL <em>ENGINEERING</em> EXPERIENCE IN BRIDGE DESIGN, BRIDGE CONSTRUCTION, BRIDGE MAINTENANCE OR BRIDGE INSPECTION.",
                     "Agency": "DEPARTMENT OF TRANSPORTATION",
                     "Business Title": "Civil Engineer 2",
                     "Civil Service Title": "CIVIL ENGINEER",
                     "Division/Work Unit": "<em>Engineering</em> Review & Support",
             ...
         }
