With the corpus defined, we can build the BM25 index. The process has two steps: tokenization and indexing. The tokenize function lowercases the text and splits on any non-alphanumeric character — so “TF-IDF” becomes [“tf”, “idf”] and “bag-of-words” becomes [“bag”, “of”, “words”]. This is intentionally simple: BM25 is a bag-of-words model, so there is no stemming, no stopword removal, and no linguistic preprocessing. Every word is treated as an independent token.
