The SolR data can automatically be facetted by different fields. The definition of the field names and the SolR stings are done in the config.ini. There is a distinct section for each domain, labeled with the the config group title [{domain_name}.facets] . On a single record retrieval facetting will return the keywords and the text facets of the record. On a record list, all keywords and text facets are included in the result.

To access a facet it is sufficient to add the facet parameter to the query string. The field names are listed with comma separation. The all value returns all defined facets. If only the facets are required, the paramter limit can be set to 0
