Agentforce : Understanding Zero Keyword Scores in Hybrid Search Results for Agentforce

Publish Date: Nov 24, 2025
Description
Users may notice that the Agentforce Retriever's Prompt Builder output returns no results, even if the prompt seems correct. This issue affects hybrid searches, where some results show a keyword score of 0, despite relevant keywords being present in the articles.
 
Resolution

1. Please note that hybrid search only considers the top 250 keyword matches from Solr. If a document is not within the top 250, its keyword score will display as 0, even though it may still appear in the hybrid results due to other factors like vector similarity, popularity, and recency.

2. If necessary, you can rebuild or recreate the search index to ensure proper indexing. However, be aware that this may not change the behavior, as it is functioning as designed.

3. Keep an eye on future Salesforce releases for any feature improvements that may address this limitation.
