Summary of Changes

Hello @AuditAIH, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request significantly enhances the Ollama integration documentation by introducing a dedicated section for rerank models. The update provides users with clear, step-by-step instructions and configuration examples to set up and utilize Ollama-based reranking capabilities within Dify, thereby improving the relevance and quality of search and retrieval results. It also offers practical advice for local deployment of rerank tools, addressing the current lack of official rerank support in Ollama.

Highlights

• Documentation Update: A new section has been added to the models/ollama/README.md file, providing comprehensive instructions for integrating Ollama rerank models into Dify.
• Ollama Rerank Integration Guide: Detailed steps are now available for configuring Ollama rerank models within Dify, covering model naming, base URL specifications, model type, and context length settings.
• Local Deployment Hints: The documentation includes guidance on locally deploying rerank tools like vllm, llama.cpp, tei, and xinference, along with a specific tutorial reference for llama.cpp with Qwen3-Reranker.
• Updated Dify Documentation Link: The link to Dify's official documentation for Ollama integration has been updated to point to a more specific and relevant section.

Code Review

This pull request updates the README for the Ollama integration to include instructions for configuring a rerank model. The changes are helpful, but I've identified a couple of areas where the documentation could be clearer and more consistent. My feedback includes a suggestion to fix an inconsistent colon style and another to rephrase the explanation for the Base URL to make it less ambiguous for users. These changes should improve the overall quality and readability of the documentation.
