Important information for upgrading AI Search to Washington DC
Washington DC Patch 9:
- After you upgrade to Washington DC Patch 9 from an earlier release, make knowledge block content searchable by reindexing all your indexed sources that include knowledge articles. For details on reindexing, see Perform a full table index or reindex for a single AI Search indexed source or Perform a full table index or reindex for multiple AI Search indexed sources.
Washington DC:
- When you upgrade to Washington DC, AI Search automatically updates your existing Genius Result configurations to use the new AI Search Genius Result Configuration form fields. This update procedure makes the following changes:
- Removes existing Genius result answer type field values.
- Migrates Genius result logic field values to the new AI Search request processor and AI Search response processor fields as appropriate.
- After you upgrade your instance to Washington DC, AI Search retains the value that you previously set for the Boolean search operator to use when a search query includes multiple terms ( glide.ais.query.search_operator ) system property. To gain the benefits of the new enhanced query mode for multi-term searches, set this system property's value to AND then OR 2+ key terms. For details on AI Search system properties, see AI Search system properties.
- Starting in Washington DC, the User [sys_user] table defaults to sorting indexed records by their sys_created_on dates instead of sorting them by their sys_updated_on dates. This change requires reindexing of the User table indexed source for AI Search, which can be time-consuming. When you upgrade to Washington DC from a previous family release, AI Search does not automatically reindex the User table indexed source. If you need to be able to search the latest configuration for user records, you can manually reindex the User table indexed source, which may take some time. Otherwise, AI Search will reindex individual User table records as they're updated until all records have been reindexed.
New in the Washington DC release
- (Washington DC Patch 9) Knowledge block content indexing
- When you index knowledge articles for search, AI Search now includes content from knowledge blocks to improve search recall.
- AND then OR 2+ key terms option for multi-term search queries
- Improve search performance for queries with two search terms using the new AND then OR 2+ key terms value for the Boolean search operator to use when a search query includes multiple terms ( glide.ais.query.search_operator ) system property. When this value is set, AI Search only performs automatic query resubmission if the search query includes more than two search terms after stop words are removed. AND then OR 2+ key terms is the default value for instances zBooted in Washington DC.
- Natural Language Query Genius Results
- Surface relevant search results from large source tables by adding Natural Language Query (NLQ) Genius Results to your AI Search applications. NLQ Genius Results interpret your searches using plain language to find source tables with relevant results. The NLQ Genius Result answer card displays the suggested source tables, combining results from Analytics Overview and CMDB table queries. You can preview records from each suggested table directly from the Genius Result answer card.
- Semantic vector search
- Find results that match the meaning and intent of your search terms. Semantic vector search is an alternate search mode that overrides the default lexical search mode. Now Assist in Virtual Agent uses semantic vector search to retrieve Catalog Items and topics. Now Assist in AI Search uses semantic vector search to find cached answers for Now Assist Q&A Genius Results.
Changed in this release
- Synonym matching and expansion retains terms defined as stop words
- When evaluating synonym matches and expansions, AI Search retains search query terms defined as stop words. This behavior helps ensure that synonym matches return consistent results no matter which version of a synonym a user searches for.
- Field changes on AI Search Genius Result Configuration form
- On the AI Search Genius Result Configuration form, the Genius result answer type choice field has been removed. The Genius result logic script field has been replaced with separate AI Search request processor and AI Search response processor script fields.
