The Ghost Update
Fast typing sometimes replaces fresh search results with results from an older request.
The bug report
You get the whole project — a React front end, an Express API, and Mongoose models — opened in a browser editor. Reproduce the symptom by reading the code, change what’s wrong, and run the hidden tests to prove it.
What the fix must prove
- shows results for a single completed search
- keeps results for the most recent query
- rejects when the search service fails
