Instance specific key.

Search term entered by the user.

Maximum length: 100

The category that should contain the filtered results. If you want to provide the entire path, you should include the categories divided by a hyphen (-).

Example: ?tn_cid=100-150

Specify the language to use for the search algorithms.

All available languages can be retrieved with the catalog call: /catalog/languages/{instancekey}

Example: ?tn_lang=nl

Hidden parameters can be added to the URL by using the parameter 'tn_parameters'. The key is the facet URL-name. The value is the facet value that should be applied. When using multiple values they should be separated using a pipe (|).

When filtering drinks by property 'brand' with value 'Coca Cola' or 'Pepsi' and 'volume' 1L or 1.5L, the value of tn_parameters should be: brand=Coca Cola|Pepsi&volume=1L|1.5L

Example: ?tn_parameters=brand%3DCoca%20Cola%7CPepsi%26volume%3D1L%7C1.5L

Hidden exclusion parameters can be added to the URL by using the parameter 'tn_parameters_except'.

This is used to exclude certain parameters from the results (show everything except specified parameters)

When filtering by property 'brand' with value 'Coca Cola' or with value 'Pepsi' the value of tn_parameters_except should be: brand=Coca Cola&brand=Pepsi

This value should then be URL encoded.

Example: ?tn_parameters_except=brand%3DCoca%20Cola%26brand%3DPepsi

Specify the keyboard to use for the search algorithms.

All available options are: 'qwerty', 'azerty' or 'qwertz'
