Requires Now Assist in AI Search 15.0 or later. * **Indexed Source Guardrails:** Limits on Task and Alert records indexed enhance search performance by controlling index size. * **Search Source Exclusion:** You can exclude specific search sources from regular search results, Genius Result answers, or both within search profiles, including optional exclusion of attachments. * **Synonym Dictionary Boosts:** Define synonyms and apply relevancy boosts or penalties to improve search result ranking. * **Fuzzy Numeric Search:** Find records by numeric terms without needing exact prefix or leading zero matches. * **NLQ Genius Results:** Supports searching multiple CMDB tables with user-selectable dropdowns for terms that match multiple tables (introduced in Xanadu). * **Japanese Language Support:** Enhanced precision for Japanese phrases containing the middle dot (nakaguro) character preserves term separation during indexing and searching. * **Improved Search Interfaces:** Consumer-grade search experience updates for global, workspace, and portal searches include replacing navigation tabs with source facet buckets, opening results in new tabs, and improved facet display controls. * **Now Assist Multi-Content Response Genius Results:** Supported in global and workspace search when Now Assist is installed, overriding other Genius Result configurations for consistent answer delivery and integrated Virtual Agent topic citations. * **Search Suggestions and Admin Tools:** Granular aisadmin role enables access to Search Suggestions tables without full admin rights. The refreshed Search Preview UI allows administrators to preview and tune search behavior with keyword or hybrid modes and detailed analytics. ## Important Upgrade Considerations * After upgrading to Xanadu Patch 3, reindex all indexed sources containing knowledge articles to include knowledge block content in search. * To add dashboards, data visualizations, and KPI navigation tabs to AI Search for Next Experience, update the relevant ServiceNow Store application to version 4 or later and apply the provided update sets. * Review and configure new guardrails and exclusion settings post-upgrade to optimize search performance and relevancy. * Hybrid search mode requires enabling in Now Assist in AI Search 15.0 or later. ## Changes * **Facet Refinement Filters:** Facet filters for reference fields display translations in the search user's language if available, defaulting to system language otherwise. * **Late Binding Security:** Preserves accurate click rank signals by correctly removing inaccessible results. * **Search Results Page:** Updated for global, workspace, and portal searches with consistent UI changes, including facets shown as buckets, removal of search term highlighting, and opening results in new tabs. * **Attachment Result Display:** Grouped attachments now collapse under parent results with "Show more"/"Show less" controls for better space management. ## Deprecations The External Content Q\&A Genius Results feature is marked for future deprecation starting with Now Assist in AI Search 8.0 and remains supported until officially removed. Customers should monitor related documentation for updates. ## Activation and Requirements * AI Search is active by default in both Xanadu and Yokohama releases. * No new additional requirements or browser incompatibilities have been introduced beyond existing ones. * AI Search does not support Internet Explorer; for best performance, use the latest versions of Google Chrome or Mozilla Firefox. ## Localization and Accessibility * AI Search supports indexing and search in all ServiceNow AI Platform languages. * Features like stop words and synonyms are available in many supported languages. * No new accessibility updates were introduced in Yokohama. ## Practical Benefits for ServiceNow Customers * Enhanced semantic and hybrid search capabilities provide more accurate, context-aware results, reducing time to find relevant information. * Improved indexing of knowledge blocks and support for Consolidated page of all release notes for AI Search from Xanadu to Yokohama. ## How to use this page To help you prepare for your upgrade, we have combined the cross-family AI Search release notes onto one page.
