Implement full-text search with IndexedDB
What you will learn
Use index.openCursor with IDBKeyRange โ full table scans (getAll) are OK for small stores, deadly for large
Compound indexes ([category, date]) support multi-column queries; single-column indexes cannot answer them efficiently
Test empty result, single match, key boundary matches โ cursor paths diverge on each case
