In all documents about gazelles, the following values are set for the keyword metadata key:

Document keyword value 1 keyword value 2
Gazelle Definition mammal Africa
Gazelle Etymology and Name mammalia Middle-East
Gazelle Species Africa viviparous animal
Gazelle Prehistoric Extinctions viviparous africa

The keywords related to the type of animal are useful, but those referring to a geographical location are not.

If documents are published as is, the keyword facet values are displayed in Fluid Topics as follows:

Facet values before removing the Unclassified Values

ADMIN and KHUB_ADMIN users can clean facet values so that only the most useful ones appear as follows:

  1. In the Vocabularies administration interface), create a new vocabulary named keyword_clean to apply the following synonyms:

    • Mammal=(mammal, mammalia, viviparous, viviparous animal)
  2. In the Enrich and Clean administration interface, configure a new rule.

  3. Select the Remove unclassified values option.

  4. Set the keyword metadata element so that it appears on the portal. See Declare metadata.

Since the Africa, africa, and Middle-East values are not mentioned in the keyword_clean vocabulary, Fluid Topics ignores them when creating the facet.

The following screenshot shows the result of cleaning the keywordmetadata value in Fluid Topics:
