Apache Lucene
(https://lucene.apache.org) 📸 Data Snapshot: May 25, 2026Inspect the JSON-LD. Is there an Organization or Person schema, and does it carry sameAs links to real external profiles (LinkedIn, socials)? Missing schema or no identity declaration signals an anonymous entity.
Authority is firmly established through the association with the Apache Software Foundation (ASF). The site references the Lucene PMC (Project Management Committee) and specific developer benchmarks, providing a clear digital footprint for its claims. The technical implementation is robust, with a clear heading hierarchy and detailed CHANGES.txt logs for every version, compensating for the lack of formal Organization schema.
Performance claims are not only substantiated but are tracked in real-time through nightly benchmarks. The claim of 40% speedup on disjunctive queries in version 10.3.0 is cited directly against Lucene’s nightly benchmarks, representing a rare level of transparency. The site demonstrates performance through its release logs (e.g., 2-bit quantization providing better recall than 4-bit) rather than asserting it via marketing copy.
Identity & Authority is read from the structured data first: whether the site declares who it is in machine-readable schema, with verifiable identity links. Below is the schema captured per page, then the external proof links that support (or fail to support) that identity.

This page presents a snapshot of public data from Apache Lucene, captured on May 25, 2026, to show how machine logic reads Identity & Authority signals into an AI reputation evaluation.
Purpose: This data is presented under “Fair Use” for the purpose of independent signal analysis, allowing readers to see the raw signals behind the reputation score.
Notice to Apache Lucene: This analysis is part of a non-adversarial audit conducted by 1 Euro SEO. The results are intended as professional feedback to help improve any website’s machine-readability and authority signals. The evaluation is free, and any company can request a fresh audit at any time.
Any company can use the insights for free and improve its voice. When a company has updated its content, it can always submit a new audit request, which will be reflected in a new current score.
