Practical Use for ServiceNow Customers
By utilizing these dictionary forms, you can tailor AI Search to better handle typographical errors, ignore irrelevant stop words, and recognize synonyms specific to your organization’s terminology. This customization enhances search results accuracy and user experience. The ability to derive typo corrections from your indexed content automates dictionary maintenance while blocked fields ensure unwanted terms do not affect search behavior.
The Dictionary and AI Search Dictionary forms contain information about your AI Search typo handling, stop word, and synonym dictionaries. Use these forms when creating or modifying a typo handling, stop word, or synonym dictionary for use with AI Search.
For details on creating and modifying dictionaries, see Modify settings for a typo handling dictionary, Create a stop word dictionary linked to a search profile, and Create a synonym dictionary linked to a search profile.
