Some searches support faceted search and filtering. This can be used to obtain more details about the filters available and provide a better user experience

Fetching the faceted filters

Information about faceted filters will be returned as part of the same search response, if enabled.

URL : /SearchService.js

Method : POST

Auth required : Yes

Required parameters

NameExampleDescription
SearchNameDigiZuite_System_Framework_SearchFixed parameter that identifies the endpoint search.
configfacet=trueEnables the faceting search.
configfacet.limit=101Limits the number of options returned for each filter .
config
facet.field={!ex=sAssetType}sAssetType
Enabled faceted result for the filter sAssetType. A list of all filters can be obtain using the DC 5.5 GetVisibleSearchFields endpoint.
configf.sAssetType.facet.sort=count

Sorts the options returns or the sAssetType filter. Available values:

  • count - sorts the options by usage(most used to lease used)
  • index - sorts the options alphabetically
accessKey2d8319f4-7a57-4ca0-a027-c44c2f259aacAccessKey for API

Optional parameters

More than 1 facet fields can be added to a search.

It is recommended to avoid faceting field of type date(datebetween) as they increase significantly the size of the search response.
