Yokohama Patch 3 Improve semantic search with third-party embedding models Use custom and third-party embedding models supported by the AI Search RAG application to generate more accurate and relevant semantic search results. Yokohama Early Availability Limit the number of Task and Alert records indexed with indexed source guardrails Index guardrail settings restrict index size and increase search performance by limiting the number of Task and Alert table records indexed for search. Exclude search sources in a search profile from search result or Genius Result generation Tune your search results by configuring search source exclusion settings in your search profiles. You can exclude a search source from being used to generate regular search results, Genius Result answers, or both. When excluding a search source's records from Genius Result answer generation, you can also choose to exclude its attachments.

Administrators can disable indexing of knowledge block content if desired. Boost relevancy for search results that match synonyms from a synonym dictionary Define synonyms in a synonym dictionary and configure a result improvement rule to apply relevancy boosts (positive or negative) to search results that match any of those synonyms. Customize semantic indexing settings for indexed sources Customize semantic indexing settings for your indexed sources. Fuzzy numeric search Find records by their Number using numeric search terms like `23583`, with no need to match alphabetical prefixes or leading zeroes.
