Google's high standards for search engines have made users expect instant answers, leading to the development of Alexis, an application that uses Redis as its main database to provide fast and efficient search functionality. Alexis leverages RedisAI and RediSearch to retrieve information from a corpus in response to a query with maximum efficiency, allowing users to index PDFs and extract information with ease. The application uses NodeJS with TypeScript in the backend and React with TypeScript in the frontend, with a webserver exposed through the Express framework, including endpoints for user registration, login, logout, and querying documents. RedisInsight is used to visualize the data and optimize the Redis application. The application provides an efficient text ranker capable of retrieving search queries at maximum speed, allowing users to make relevant searches and receive instant answers.
