Elastic announces GA of cross-project search on Serverless, enabling teams to query across all linked projects without moving a byte

This post announces the General Availability of Cross-Project Search (CPS) for Elastic Cloud Serverless. Key technical contributions include: support for up to 100 linked projects by default, enabling existing serverless projects to query across linked projects without migration, extending ML jobs and APM anomaly detection to span linked projects, and enabling AI agents to retrieve context from multiple linked projects. It also details the serverless-native approach, contrasting it with Cross-Cluster Search (CCS) in Elastic Cloud Hosted, and outlines the pricing model for mounted data and egress. The post also introduces a new user role for programmatic CPS access.
