Better Vector Search for Long Documents: Chunking Inside Manticore Searchnew

Manticore Search added automatic document chunking for vector columns, lifting long-document recall@5 from 55.1% to 83.3% in its benchmarks.

Manticore Search introduced a chunk_strategy option for model-backed vector columns in CREATE TABLE, offering five strategies (truncate, mean, fixed, recursive, sentence) with tunable max_tokens, overlap_tokens, and max_chunks, eliminating external splitters and separate chunk tables. On its 189-page, ~298k-word manual, sentence chunking improved recall@5 from 55.1% to 83.3% and MRR from 0.44 to 0.70, at roughly 2.5x RAM and 4x ingest time. Documents still return as single results; queries are never chunked.

AWS’s new sign-up gives accounts spend caps, email invites, and agent-set permissions

AWS's new sign-up flow gives fresh accounts agent-configured permissions, email-based team access, and per-project monthly spend caps starting at $20.

New AWS customers can sign up with Google, GitHub, or Apple identities, start with $100 in Free Tier credits, and build inside a project where AWS and coding agents automatically configure permissions and install tools like the AWS CLI and Agent Toolkit. In a demo, an agent deployed a Lambda function, DynamoDB table, and API Gateway endpoint without any manually written IAM policies. Paid projects get monthly spend limits starting at $20 that pause the project when reached, and the gradual rollout applies to new customers only.
