Création d'un moteur de recherche (Parsing de la collection, Index + Index inversé, Ordonnancement, Ranking)
This project implements an in-memory search engine for indexing and retrieving documents from a CSV file using Python and NLTK. It preprocesses text, builds an inverted index, and ranks documents based on relevance to a query using the Okapi BM25 algorithm.
