    • The Semantic Index Field form enables you to define a semantic index field for use in an AI Search semantic index configuration.

    To learn about defining and modifying semantic indexing settings for an indexed source, see Configure semantic indexing settings for an indexed source. For details on semantic index configuration fields, see Semantic Index Configuration form.
    Note:
    This form is only available when the AI Search Semantic Controller plugin (com.glide.ais.semantic_search) is active on your instance. To activate this plugin, your instance must have at least one Now Assist application installed.
