    Fetch Results

    For any primary query to your search platform, you can perform a secondary query to Never Null and get results that enhance your own. This topic shows you how to construct and send a secondary query to Never Null’s REST API using the Solr query language.

    To use the API, you need these items from Lucidworks:

    • Your short customer name

    • Your query profile name

    • Your credentials

    If your content was recently ingested for the first time, Lucidworks will inform you when the initial model training is complete and your Never Null data is ready to query.


    Before you can begin fetching Never Null results, you must log in to the service as shown below:

    curl -i -H "content-type:application/json" -X POST -d '{"username":"username","password":"password"}' ''

    Never Null returns a cookie, as in the example below:

    The response is a JSON response where each item includes these fields:
