Formulate a hybrid query

This tutorial demonstrates how to use hybrid queries.

Procedure

Qualified and free form input can be combined. This can be helpful, for instance, when the end-user inputs the free-form text into a single search box while the application provides the structured elements in the background for local focus.

Another example, when the application provides to the end-user an input box for a free-form address text and e.g. a drop-down box for postal codes.

The address query 141 Boulevard Émile Thomas with postal code set to 83300 can be formulated with the following:

GET https://geocode.search.hereapi.com/v1/
    geocode
    ?q=141+Boulevard+Émile+Thomas
    &qq=
        postalCode=83300
    &apiKey={YOUR_API_KEY}

The following parameters are used:

• q - Enter a free-text query.
• qq - Enter a qualified query. A qualified query is similar to a free-text query, but in a structured manner. It can take multiple sub-parameters, separated by semicolon, allowing to specify different aspects of a query.
• apiKey - Your API key.

The response to the above request looks like the following:
