Worked on enhancing the apache/doris-website repository by delivering comprehensive documentation for the Doris inverted index feature in version 3.1. Focused on aligning technical content with the latest product capabilities, the work detailed new tokenization methods such as icu and basic, introduced dict_compression, and described the updated V3 storage format. Using Markdown and technical writing skills, the documentation clarified usage for both developers and operators, improving onboarding and self-service support. The approach emphasized clear, versioned references and explicit descriptions of v3.x APIs, ensuring that the documentation accurately reflected the evolving feature set and supported effective engineering workflows.
