🔍 Whoosh

What is this? This page loads Pyodide (CPython compiled to WebAssembly), installs the real Whoosh wheel with pip, builds an in-memory index from a small corpus, and runs your queries — with BM25 ranking and result highlighting — with no server. That's the whole point of Whoosh: it's an embedded, pure-Python search library.

Because Whoosh is pure Python, the same code runs on your laptop, your server, PyPy, and (as you can see) the browser.
