Non-vector-based AI document search engine
PageIndex is a document indexing tool that works with reasoning capabilities without the need for vector-based search methods. Instead of traditional vector databases, it optimizes RAG (Retrieval-Augmented Generation) processes by using text-based logical inference.

Installation
pip install -U pageindexIf you don't write code
I want to index a document in local mode using the PageIndex Python library and search the document using an AI model. After completing the installation, can you run the sample Python code that allows me to define my OpenAI API key, upload the document to the system, and ask questions?
Repository: https://github.com/VectifyAI/PageIndex. Follow the official instructions in the README of this repository for setup and execution.
Before starting, check which OS we are on and if the necessary tools (e.g., Python, Node.js, Git, Docker) are installed. Install any missing ones step-by-step according to this system.
Create a new, empty folder to work in. Do not touch any files outside this folder and do not delete anything. Tell me what you are going to do in one sentence before running each command.
If an API key is required, do not ask me to type it into the chat. Show me how to add it to the .env file and ensure this file is not pushed to Git.
Tell me what I should see on the screen at the end of each step. If an error occurs, I will paste the error message to you exactly as it is, and we will fix it together.
