Now Assist Q&A Genius Results send eligible knowledge article search results to the Now LLM Service for Q&A Genius Result answer generation.

By default, the system only sends knowledge article results to the Now LLM Service when the search satisfies all of these conditions.

• The search application is Service Portal, Virtual Agent, Employee Center, or global search.
• The user's session language is English.
• The search contains two or more terms.
• The search matches the Java regular expression pattern defined by the sn_ais_assist.u_question_regex system property's value. This system property has no value set in the base system, so by default all search queries satisfy this condition.

You can customize the pattern match condition by defining your own Java regular expression pattern for use by Now Assist Q&A Genius Result configurations.
