Restricting to a main category

As the Navigation module works with exactly the same data as the search, the navigation of the product range corresponds to a given filter or combination of filters over the entire product range. The types of fields filtered here are key. There are two types of fields in FactFinder:

Simple data field

Each simple data field contains the information stored in a single level. A FactFinder environment that uses this type of category structure has several associated fields that make up the hierarchy. Normally, these carry the same name and are differentiated by a numbering scheme (such as Category0, Category1, Category2).

Example data:

Field name	Database content
category0	Clothing
category1	Trousers
category2	Jeans

Category path field

In this case, the complete navigation hierarchy is stored in a specially defined FactFinder category path field. Please be aware that the database content does not correspond to the content of the export file (details concerning the export format can be found in the Export documentation).

Field name	Database content
category	|Clothing/Trousers/Jeans|

Filtering for a simple data field

The default name of this sort of field in FactFinder is category0. If you want to navigate (filter) to the category with the name Clothing, the navigation call must pass a filter parameter with the name filter=category0:{value} and the value Clothing. A corresponding call to the REST interface would be:

..rest/{apiversion}/navigation/{channel}?filter=category0:Closing

Filtering for a category path field

If you want to navigate a data field that contains a category path, the navigation call must pass a filter parameter with the name filter=category:{value} and the value Clothing.

In relation to the example above, a corresponding call to the REST interface would be:

$stringEscapeUtils.escapeHtml($body)
